I've been on the MTN network for about a week now.
Can't really say anything is worse. Yes, no more free NZB server, but no train smash, as we mainly rely on streaming on our Roku.
I spent the whole day online today, as I was home on study leave and browsing forums and taking mock tests online, etc.
Throw in the occasional YouTube video as well.
Must say, that the daytime browsing was much better than it was on IS.
International ping is amazing though. Getting 170ms - 180ms pings to bbc.co.uk and the UK Unotelly server 176.58.107.53
Local ping could be better. Pings to hetzner are always around the 40ms - 50ms mark.
Although, the only downside I have since being moved to the MTN network is it seems as if the streaming isn't as good as it used to be. Used to be able to stream a 720p vid from YouTube without any buffering. It plays fine, but there's the occasional buffer now. Also, tested a Hulu video on my laptop now, instead of on our usual Roku, and it seemed that it was hovering around the 1Mbps - 2Mbps range. Where previously on the IS network, it would max out my 4Mbps connection easily. Especially on YouTube, if you use the stats for nerds. It now is constantly in a 1.5Mbps - 2.5Mbps range. Maybe there's just some tweaking that OpenWeb needs to still do.
So, at this stage I'm still busy testing it to see what is the best for me. Looks like both have their positives and their negatives. Lower contention, better daytime browsing and lower international ping on MTN.
Better streaming, Free NZB Server and lower local ping on IS.
