I would go for the best frame within my budget.
I used to build with Ultegra but now I use 105 I can't tell the difference, Ultegra is probably a bit lighter but not much.
Relatively low end group sets are so good nowadays it’s very difficult to begin to justify anything above 105 level for the average cyclist.
But when did that stop many of us?![]()
