I use Line 6 G90 (rack mount) with my Axe FX3 and the Line 6 G50 for my AX8. I have another G50 unit ready for my FM9 when I finally get one. I have 4 transmitters between the rigs, all on the same channel (I don't use the rigs at the same time). I get the Shure right angle 1/4-inch cables for the transmitters.
I like being able to have all 3 of my guitars at a gig have transmitters in their pouch, ready to go. When switching guitars, I just have to turn off the transmitter as I put the guitar on the rack and turn on the transmitter on the guitar I'm picking up. Makes for quick switches, which happens if you break a string on a Floyd Rose guitar (can't just play with 5 strings on those guys).
I also play wireless 99% of the time, even at home. I won't perform live with a cable if I can help it (I've had some bad experiences with tripping) and using the same wireless at home as I do while performing reduces the chance that my tone is different between dialing it in and performing. I have rechargeable AA batteries that I use to keep cost/waste down.
Overall, I am very happy with the performance of the G50/G90. There have been a couple stages that I had issues with it, though. If I didn't have the units anymore and was starting over, I might look into what else is in the market since the Line 6 stuff has been out there forever.
