I'm in the same camp. My game is house-ruled Labyrinth Lord (some LotFP elements).
How much are you using? Are you using all the rules from the Basic Rules?
I'm not using the new XP table, or the Inspiration rule yet. I also haven't adopted the new short term rest healing rules either.
I actually had a house-ruled Dying Rule to roll to stabilize, get a permanent injury, or die if they went under 0 hp, so the only difference now is that they roll 3 times instead of once.
My PCs were very happy to get the ability modifier boosts, the HP increases, and the extra ability/spell each of them got.
