Judging how you don't know vape doesn't have cpvp, just go with Meteor to start. Don't waste your money on something you might lose interest in.
If you still want better than Meteor after a month or so then you can buy a better client, you'll find opinions from the servers you play on and...
well you could say 'oh i got that a while back but I don't use it anymore' and they would have to unban you as they don't have any proof other than a cosmetic, assuming you aren't just bhoping setting off alerts like mad.
