Well always choose two kinds of fighting style like bow and sword or magic and sword.
And all styles become repetitive...but that's not a bad thing since it stays fun for me.

Mage can at least mix things up and change styles. Everything else is really samey.

Mages

I think archery is the least repetitive, something about it just keeps me interested. Saying that im a svcker for mixing some magic up for fun! Melee is the most repetitive, but thankfully ive finally got my one hand and two handed maxed out!!

I'm a shield and conjuration mage with like 10 followers so my fights are never boring. Looks like 4th of July when a skeever hits me.

Mages for sure can mix it up the most. I found my warrior to be the most repetative.

My sword and board (shield) paladin type character was probably my most powerful and also the one that got the most repetitive in the mid to late game. Just about every single fight was the same, run up, shield bash, slice and dice, bash again, finisher, done. It was very effective and very boring after awhile as nothing can really hurt you once you get your skills and equipment up to par but all the fights and encounters are very much the same as all the ones that came before.

My mage/thief Nightblade character, on the other hand, has been the most fun of all the characters I've tried. He can tackle the quests, encounters, and dungeons of the gameworld all sorts of different ways and believe me I've tried many of them so he never gets boring. I just did one of the latter Theives Guild quests last night that is supposedly nearly impossible to do non-violently without using some form of Invisibility and did so in this "impossible" fashion. Took a long time and a lot of patience on my part but I got through it without any hositle action or enemy deaths. Felt rather proud of him and myself after that one I have to admit.
