From a high level they are both good brands
Trek pricing is a little different then most bikes and you won’t be able to negotiate any discounts with trek. They do have sales though periodically. I think you pay a premium for the trek name
If a beginner i agree upgrading your current bike if you can do that and you can sell your old groupset build or buy your dream bike when you know exactly what that is
If you’re looking for the best bang for the buck for something not on sale you can order a canyon online: I think 30 days to return it. LBS may not like it though; my guy actually recommended them to me bc they just want to do service and stop selling bikes he said it’s not worth it
I would for sure look at that new specialized
Like others say, look at the wheels and whole package not just groupset
