If the components are basically a wash (read: equal) you should, in my opinion, buy the best quality/best fitting/performing frame you can afford. If you have a great frame, it’s much easier to upgrade the components as you a) break them b) can afford them or b) lust after better ones; as opposed to buying a mediocre frame with slightly higher quality components.
It’s the same idea as buying a house – buy the worst house in the best neighborhood (so long as the structure is sound), and fix it up to your exact liking as you can afford it.
Either way, you’ll have a bike and lots of fun!
