Seems I'll keep running on my WebAfrica account for now and reduce my AfriHost account to the bare minimum...
Been a very happy AH customer (still am), but the WA prices were too good not to give it a shot.
I depleted my cap on the 3rd due to work stuff, and my options were to either get additional AH bandwidth, or try out WA. Went the WA route and I must say, quite happy with their service so far. Can't really see worse throughput compared to AH (both seem to max out line speed 99% of the time), so in my case at least, price will be the deciding factor.
Also (on the WA account), I've found that running a cron job to download any "high definition Linux distros" I might desire between 00:00 and 06:00 works out great. Logging indicates that I get line speed for these downloads.
So all other things being more or less equal, 50GB vs 60GB+60GB, it's clear who's going to be the winner here...
