General

zero is really fun and strong but requires a lot of control and timing for efficient bossing. definitely a better farmer / mobber.
drk is a decent mobber and a top notch bosser.

I cant quite compare them bossing wise because I dont know the potential difference between them, but Im sure both of em are a good call for both mobbing and bossing. pick what you like the most or find more entertaining

I have a level 201 Zero

I have around 50b to spend on funding
