ECM factoring is not relevant to the current GIMPS wavefronts of activities related to finding new Mersenne primes: TF, P-1 factoring, LL, PRP, p>80M.

I think the conventional wisdom is PRP & P-1 are the best uses of cpus, and TF the best use of gpus, for advancing the wavefronts and finding the next Mersenne prime.
P-1 assignments complete quicker than PRP or LL (primality tests) on the same hardware. Consequently P-1 is more suitable for slower cpus than primality testing.
But run what makes you smile the most, and keeps you from getting bored and quitting.
Running a mixed workload is fine, and prime95 makes it easy to do so automatically on multicore machines.
