Short answer: Based on everything you've said,
I'd pick Stablehost.
Longer answer:
The networks in Dallas can get bottlenecked, so I tend to avoid it, unless I have special requirements that make Dallas
** the best location. A lot of it has to do with how much backhauling and re-routing seems to go on, and has gone on since the 1990s. I'm just not fond of servers in the metroplex. (I'd do Kansas City or Chicago, if I wanted a centralized North American location.)
I think California and Arizona are your best bets for Asian traffic.
From your other post, you've mentioned that
Hawkhost's Singapore route first goes to Japan before heading back out elsewhere. I don't have time to test this today, so I'll just take your word for it that you've verified this with
Hawkhost and some tracert tests. That doesn't seem overly optimal, no.
Definitely test from a non-cellular/mobile connection. Some kind of wired broadband connection is best for testing speeds.
Black Friday sometimes has good sales -- sometimes not. It's hard to say until just a day or two before the sales happen. Sometimes a "Black Friday sale" is just a normal sale price, or worse. Sometimes it's an amazing steal of a deal. Last year, Stablehost ran a steal of a deal, though it was for a one-year price, renewable at the full normal rate, not lifetime discount. I prefer the lifetime discount rates that are available weekly.
Plus I move hosts whenever I'm ready -- I don't wait for pricing that may or may not be there. I base decisions on what I know now. I'll even leave hosts that are prepaid, because money is secondary to having sites reliably online. These are online tools to me, nothing more.
Generally speaking, it's against the Terms of Service / Acceptable Use Policies (ToS/AUP) of hosts to run multiple domains from a single account, if different people own the domains. That's why the reseller accounts are available -- you can use separate accounts for each separate person. Plus security is increased, as separate accounts have isolated access. If you or your buddy make a boneheaded mistake, and the site gets hacked, only one goes down, not both. Most exploits are account-level on Linux, and everything in it gets hosed.
It's unfortunate to hear
JaguarPC has given you problems. The last issue I experienced was in April, when the datacenter had routing problem, which wasn't even
JaguarPC's fault. They're such a large host, unfortunately, that odds state a server will always be down somewhere. Though it does seem the same few people (thus the same few servers) have had issues in recent months. That's not historically representative of how they've performed in the past decade.
** There are several excellent host based out of Dallas. Evolucix, for example, which is a budget unmanaged VPS host. Or Knownhost, which has both managed and unmanaged VPS offerings.
