I would definitely buy 105 over claris.
Its a great groupset that shifts really well and stays shifting well. It's light and strong. There will be more futureproofing to it.
It will also be more enjoyable if you get into cycling. Having more gears can help you choose the right one fit the terrain without either having to push too hard or slow down and spin easy
Of course you'll have to suffer the indignation of those of use that had 5 speed and that was goid enough! I love having 11 now.
