Hello!
I am also a current owner of a Hostgator reseller in search for an alternative.
My main problems with Hostgator started earlier this year, share hosting has become really slow, downtime was increased and they seem to have a huge problem with forwarding emails to gmail accounts.
My search for reviews, recommendations for hosting brought me to your site.
I thought I should share my experience with some of the hosting companies you also suggest (or not).
Please pardon my english, it is not my first language.
SiteGround.
Overall is the company I had the best pre-sales impression of all.
They give most of the info in their website and their pre-sales chat was really good, with people that seemed to know what they were talking about and not only reading answers from a manual

Unfortunately their reseller plan, charges by cpanel, which per se it is not a problem, the problem is they only give 1 website account per cpanel and adding more is quite expensive.
On the other hand I like this policy of theirs, just not for my wallet.
But they persuaded me to choose them for share hosting for my clients.
They also seem to have the best affiliate program of all. We will soon find out
EuroVps.
Their packages seem really attractive as it does their network location.
The ppl in Pre-sales chat I talked with seemed to really know about their work, I was quite impressed.
Actually it is my first candidate to migrate my reseller (free migrate yoohoo!).
BUT, what makes me hesitate, is the lack of extended info in their otherwise very well designed website.
I need all the technical info I can get. Not the just some basic info and nice description of their features.
I dont get how they think.
There is too much competition out there, give ppl the info they need or they will pass on you like I did the first I time visited their site, I just left after a couple of mins after realizing I couldnt find further info. Only DigitalFaq insisting for their quality made me go back and have a chat with their pre-sales.
If they read this, guys, be more transparent, offer more info for your services, you loose clients this way.
StableHost.
Same problem with Stablehost.
If you go to their reseller page,the info they provide it is even less than
EuroVPS.
And they dont even have a live chat so you can have answers to your questions.
If you want to get more info (and you want because they give you almost nothing) you have to either post in their support forum or send them an email.
I decided to do the latter and 6 days after I havent got any reply.
Again, if it wasnt for DigitalFaq I would had left their website the moment I visited their Reseller Page.
It is a shame really, cause it looks like a decent company, plus I like their network.
Veerotech.
These guys give you lot of info in their website.
I really like how they present their features in a very well structured site.
They also replied very fast to my contact email about their affiliate program.
a little minus the lack of the live-chat, but I dunno, the live chat thingy is not always a cure for everything.
Big Plus they have real info on their company not just a generic "choose us cause we are good".
My 2nd in the list of candidates, and 2nd only cause their EU server is located in Uk.
Webhostingbuzz.
Another good site that gives lots of info plus they have a live chat.
That is a strong candidate as well, my only "concern" is the UK based server, but at the end this might not be an obstacle.
I think they provide more info than everyone else in my list and I like they also give a lot of info about their company.
Inmotion Hosting.
This is not a candidate, but since I have many clients that are hosted in their shared or/and VPS servers I thought I should share my experience with them.
I dont want to have a bad opinion about them, there is something that makes them likeable, I like for example how honest their support is.
But they have issues the last 2 years or so.
Their Shared server is often down recently.
And It seems they have some kind of security issues, they are vulnerable to hackers attacks. I have clients in Verio and Hostgator using Joomla or emails with relatively weak password. I know it sounds ridiculous to blame a hosting company for your weak email passwords, but its not always your choice (clients can be stuborn) and only in
Inmotion I had this kind of issues, never had a similar problem in Hostgator no matter how EIG has become.
They also dont seem to choose the right ways to protect their servers.
But, for example, I find unacceptable not to be able to setup a simple Wordpress Site because
Inmotion is using an insefficient way of preventing WP attacks by blocking the WP login.
Almost everytime I set up a WP account in Inmotion I spent a couple of days with their support trying to unlock the WP admin.
Is it lack of money? lack of experience stuff? I dunno..In any case I dont recommend them anymore, which is a shame, but they do need to check their servers issues, uptime wise and security wise .
Site5
Honorary mention to
Site5. I find them a tad expensive and there was another reason I didnt put them in my list (dont remember which though lol, after all this hosting search I lost a few brain cells) but overall they seem to be ok and the info in their site is quite extensive.
I hope my post will be helpful.
Cheers!
