PC is really the only way to go for elder scrolls games in my opinion (for example if you're a huge fan of Morrowind, the graphics have been consistantly updated through the modding community to the point where they look better than oblivion...). If you have a problem with something, there is most likely a mod for it.
I personally have not encountered any bugs with vanilla Skyrim, however you should be warned that too many mods can inflict bugs on you, especailly mods that do not work well together; you will often encounter things like texture glitches, holes, and odd AI behavior.
Since you say you have never played a bethesda game on pc before, I would suggest you stick to the Steam Workshop for mods for the time being, until you can learn how to manually install mods and how to troubleshoot conflicts. I would suggest BOSS for Skyrim as well; it is a mod sorting software that will help put mods in a load order with as few conflicts as it can, and it is constantly updated so it will give you constant feedback on what mods are out of date or conflict with eachother.
I wish you the best of luck with your new adventure; take it from a console player, when I went to the PC for Morrowind and Oblivon, I could never go back.
