Good for you! As I mentioned, this is just my opinion. I don’t live in Thailand or Cambodia. Based on my experiences, the currencies I deal with, and what we have in Europe, I found it more expensive. The flight tickets weren’t too bad, but food and fruits were more expensive than in Thailand. That was my experience, and that's what I shared.
For you, it may be a cheaper option, and you probably know the best places to go in both Cambodia and Thailand, so you're more familiar with everything.
Everyone can have their own experiences, especially when European people going there!
