What is often overseen in 5e is the Background. One of the best Backgrounds is "Criminal". It basically gives you a multiclass thief for the purpose of trap disarming and lockpicking. And it does not cost you anything, aka no level dip crap for purely mechanical reasons.There are some other Backgrounds which are as useful, depending on your class / party composition.5e is faster combat, more fluent gameplay and less headache on the table, whereas 3.5 / pathfinder has more Options as pointed out above but imho is better suited for computer games because all of the +x -y stuff. Bound accuracy leads to more realism aka low level Mobs are still a threat at least in numbers.5e compared to 3e is a bit like 2nd ed darksun compared to standard vanilla 2nd ed. You hit more often and you hit hard (and vice versa for the mobs) even without super optimized build and equipment. This makes combat intense and often shorter in number of rounds.
