I would love this level of control with the form factor / audio streaming features of the airport express.
As for your question, any 802.11 a/b/g router should be compatible with the Mac's airport. So it is really just a question of which router will give you the best range. Also you can add an external antenna to most routers to improve signal strength or add a second router/access point to give you more range. (i.e. it would simply be used as an access point and not a router.)
I've got an Airport Express (AX) I carry with me when I travel, and I use the Linksys WRV54G at home. As far as I can remember, you can't configure port forwarding on the AX. I think the other poster is correct in that you should assume that your configuration options will be limited on the AX, in comparison to the Linksys. I guess it depends on whether or not it will be your main home WAP. (Like I said I use it in hotel rooms so I can move my laptop around the room so I don't need extensive configurability..)
Having said that I agree that anyone should definitely look at WAPs on a feature by feature basis and don't worry about Mac specific support. I added the extra long antenna to my Linksys WAP and it works great. The only thing that the Mac doesn't have support for is the newer dual antenna stuff that I see Linksys and some of the WinTel laptop companies starting to support. BTW even with the Airport Extreme (802.11g) speeds, the wireless speed isn't really that great. I wouldn't recommend replacing a wired ethernet network with it and expecting to get half of 100 Mbit wired ethernet speeds. The best I've been able to get moving really big files around has been around 1/4 100Mbit wired ethernet speeds (2MB/s)
