The problem with seatguru lately (besides the pop-under ads) is that they make these recommendations not based on the actual seat as installed but rather based on theory: seats get "might not recline" by default if they're the last row even if the actual seat has plenty of recline room between it and the bulkhead. Likewise any seat immediately next to lavs gets a "lavatories may be bothersome" note even if the lav is actually so far away from the seat that there's no bother at all.

They used to take user-submitted experiences (I once had them add a note about a missing window in a KL 733) but haven't done that in a long time.
