I enjoy both. They scratch different itches.
D&D 5e is really streamlined. There are still cool things to do, but there’s fairly little number crunching to do: you figure out your to-hit bonus once, and you’re more or less done for a month or so of play. You focus on description, on choosing which cool power to use, on moving the story along. I’m running it for three kids ages 7-9, and they’re having a blast.
Pathfinder is really complicated. My fourth-level bloodrager has a three-page spreadsheet that I use, because programming it is easier than remembering exactly what changes when I rage (to hit, damage, armor class, CMD, CMB, intimidate check, climb check–and my damage bonus on my armor spikes changes differently from my damage bonus on my lucerne hammer, and my intimidate check only changes because of a feat I have, and my combat maneuver defense is changed by three different stats, one of which I wasn’t aware of, and so on and so on). Add in a casting of enlarge person (changes all those things plus weapon base damage), which will be pretty common, and use of power attack (changes damage bonus in a different way for my armor spikes, my lucerne hammer, and my chakrams), and you can see where a spreadsheet becomes helpful.
On car drives I can turn off my radio to muse on feat progression: do I want to take signature skill at fifth level and save power attack for sixth, when I get a bonus feat with limited utility? Do I want power attack at fifth and combat reflexes at sixth, with a quicker attainment of some of my best tricks but less awesomeness at fifteenth level, or do I delay awesomeness now in exchange for improved awesomeness at 11th level? I’ve got five different full feat progressions I’ve considered for the character.
Bloodragers are one of the simpler classes to play in Pathfinder :).
So, what are you looking for? Something really ridiculously complex that satisfies your urge to make spreadsheets? Or something simpler, with a lot less room to geek out about the numbers and a lot less novel shiny toys, that moves the game along quickly?
Both games are great at what they do, IMO. Depends on what you’re looking for.
