I have both these rigs fully accessorized. The 515 has the sherwood

Sherwood's SE-3 Synch Detector with both rigs. I'm contemplating (lighlty)
to sell one of them but I"m having a hard time with choosing. They are both
unique in their own way. Both are 5-Star rated receivers. What do you guys
think?

Tough decision.

I have both. As far as performance goes, I think the R7 has the edge.
The R7 has a notch filter and the 515 doesn't. The R7 has a good noise
blanker, while the 515's noise blanker is generally useless. The R7
seems to be more sensitive at lower frequencies. However, the 515 is
built like a tank and should last longer. My R7 has had 2 component
failures already, while the 515 just keeps on truckin. New receivers
come and go, yet none of them seem to have the "magic" of the R7 and
515. Maybe it's because they're both real radios instead of computers
with RF circuitry thrown in.

Just out of curiosity, what component failures have you had?

Something in the band switch circuitry and something driving some of
the LED segments (I forget the exact components, maybe a cap and an
IC?).

OK. I had a diode go out in the power supply of my original R7.
