Default Factory PCM vs. Aftermarket

So, I've been trying to learn late model tuning with HPTuner. It's more complicated that I thought it would be. I removed the torque management, changed PE, etc. on my '04 GMC 2500HD. I still haven't messed with fuel VE map, MAF, and timing tuning. Watched a lot of videos and read a lot. Partly being lazy I guess. So how much easier is tuning with systems like Holley Terminator X and similar?
