I'd personally lean toward one with a hip belt, however I think the ones you linked seem a bit over kill and heavy (I did not look at the product specs tho). I know a lot of the budget European airlines limit you to about 20lbs as a carry-on.
I found this that looks to be modeled off a Gregory pack and seems a little lighter weight: https://www.amazon.com/Internal-Resistant-Waterproof-Lightweight-Traveling/dp/B07MK299YP/ref=mp_s_a_1_7?keywords=40L+backpacking+backpack&qid=1556155207&s=gateway&sr=8-7
The most important thing IMO is that the pack fits you properly and distributes the weight well. If it doesn't you might as well just take your EDC. Hope this helps, and hope you have an awesome time in Europe!
