just to verify a few things max cape actually does have ever so slightly worse stats than death cape HOWEVER the max zone is very nice (like cfghc said) and death cape is very expensive and really not worth having if you have max cape in my opinion, as the money from the death cape could be used somewhere else for a more significant upgrade.
As for prestiging, the amount of points you get totally depends and varies on which skill you prestige. Harder to train skills give more points, combat skills give very little as they are so quick to train and as far as I know it's best to prestige at 99 not 2b.
Believe me, there's a lot I wish was fixed too. Thanks for the suggestions
