I'd agree, #2 is clearly a bit stronger in a long game. It also avoids the difficult T/M dual class, in which timing is everything. It is also slightly more balanced for archery, as I assume your F/M/T's fighting contribution will be mostly with ranged weapons.
#2 is also quite similar to my party that's rocking HoF (insofar as that's possible).
In contrast, #1 gives more melee punch with a SC fighter and stronger magery in the mid-game. #2 has stronger archery and is more versatile. If not playing on higher difficulty levels, be prepared for the F/M/T to level up at most once per Chapter.
