Community
Gentoo is friendlier all around. Especially to newbies. The Arch user community also tends to be friendly to intermediate users (but not necessarily to newbies). The difference between the two for intermediate to advanced Linux users in my opinion is more with the developer and administrative communities in regards to how they see and treat users.
To demonstrate I am just going to post an excerpt from the Arch newsletter/magazine in it's entirety with my added emphasis:

Arch Is Not a Democracy
Every once in a while someone says that there should be a public vote on the way Arch Linux is run. A common response is "Arch is not a democracy" In a democratic society, the majority opinion rules. This is not the case in Arch. There has been a lot of majority opinion bouncing around in recent times that is not ever going into the Arch Linux core as defined by the developers.
Arch is really a "Cooperative Anarchy". Anyone is free to do anything they like with Arch Linux, excepting the few copyleft restrictions enforced by the GPL. This means that anyone who doesn't like the current direction the Arch Linux development team is taking the distro can start their own development team and run their version exactly the way they want to. Neither team would be "more official" or "more legitimate" than the other. Ideally, this would occur with a certain level of cooperation between the two (or multiple) teams, with no hard feelings, but this is not a requirement. Thus, everyone can be satisfied and no vote excluding some users' opinions is required.
The Arch development team itself is a "Voluntary Oligarchy". The Arch developers have chosen to develop this distro in a way that suits them. Nobody but the developers has input into what goes on in official Arch development. This is their linux distribution and they have been kind enough to share it with the rest of the world in case someone else likes it. The great thing for users, however, is that they get to choose whether or not they are governed by this group of people.
Users that don't like the way Arch Linux is developed have two simple choices:
Use a different Linux distribution or operating system.
Develop Arch into what they want it to be.
As I mentioned last month, the second option does not require forking Arch. You can create custom repositories of community contributed tools based on, but independent of the Arch Linux core. So next time you think your voice should be heard in a democratic fashion, remember that you are already your own personal Arch Overlord and are free to do with this distribution exactly what you wish.
To be fair it isn't nowhere near as bad as the portions I added emphasis to suggest. However the general attitude is there to varying degrees everywhere. Basically if you are not writing code or participating in a high level such as the administrative staff you are "along for the ride". More than one user has actually commented on this sense that they feel "isolated" from what happens in the distro because they aren't part of a certain "in clique". For most common users this does not bother them at all in the slightest. At least not until something goes in a direction they are strongly against and where they feel they have had little input into things.
Conclusion / tl/dr: Gentoo in contrast seems more user centric and balanced (though of course not perfect). There are whole administrative structures in place with clear policies and procedures to address issues. In a word it seems more "professional". This difference in philosophy I think often becomes apparent in the end "product".
I was going to go into some more differences and observations but after previewing what I have so far I don't want to be "that guy" posting a 50,000 word reply. I'll just stop here.
