I ride both, it depends where I’m riding and why. FS is great all day in Wales, you get less tired and it has a talent compensator element to it. Hardtail forces you to ride it more actively (ie no talent compensation), its fun but more tiring in some ways I think. Then again are you comparing a heavy FS with bad pedal dynamics? go the hardtail
Hardtail is way easier to clean. You will generally get a better component spec for similar money.
I dont think I could choose one or the other. If you had too I’d say hardtail since you probably arent riding as much? then again when I only had one bike it was a FS.
Would it be like saying you dont need a sports car if you mainly drive to work in traffic and only use the “sport” element once a month? You dont need it, but its fun when you have it!
