The uphill, downhill people movers through the "stems" are bad. But for all the faults of T1 - and there are many already listed, but lets add having only one food vendor near the gates of each stem - I found FRA even more confusing, and without AC in mid-July. It hadn't been on my itinerary, but a ground hold at ORD meant my original 6pmish UA flight to CDG left without me, so I was re-routed via the 10pm to FRA. Coming off 4 extra hours at IAD looking for a normally priced meal (thank your favorite deity for Potbelly) the FRA sauna was a nice bonus.
