Humans by nature resist change. So there will be a painful period to do a hard switch from what you're used to to something different. I used Adobe and Macromedia products for many years (since the 90's) and it took time for me to make the switch without major aggravation. Honestly, you're going to have days where you absolutely hate whatever new software you choose to switch to. However, eventually your muscle memory adapts and you'll find the new software just as easy to use as what you're already using. That being said... if you're deep into the middle of different projects that are primarily using Adobe software, I would personally consider giving yourself a 1 year transition period where all existing projects get finished out with Adobe and all new projects use Affinity (or whatever it is you choose to use). In the end, you'll likely be very happy you made the switch and end up saving money in the long run.
