I wouldn't say there is one staker that's better then the rest. It really depends on how much time you wanna put into the account. You can go for a verac staker with 70 att 30-40 strength and 70 defence or maybe a boxer 80-80-80. I suggest you stay 1 prayer/summoning. Theres a lot of different variations maybe check out some youtube videos and see what you like, think you can make.
