Chris,
The Shoestring grooves kinda like an old pattern ship, where I think the RV-4 will get buffeted around by the wind alot more. My Shoestring will outclimb most RC planes other than models set up to hover. The Shoestring will knife edge from horizon to horizon at like 100 MPH and perform extremely large loops, along with true pylon racing turns at full tilt boogy (reinforced wing). 
Other than both of them having a cheek cowl, and tail dragger configuration, I do not think there is much of a comparison. THe Shoe would litteraly fly circles around it, atleast mine will.
Last fall here in WI, I was flying with three sport turbines at an IMAA flyin. My Shoe was right with them in the pattern. That day I was running 11 x 9 @ 12,300
I heard people mentioning that little Yellow plane that goes like a bat out of Hell everytime I went up, I flew seven flights that day, most people did not even fly because of the 20+ mph wind running directly down the runway.
With a .91 4 stroke, you are only going see about 60 mph with a 14 x 6, and about 50 mph with the 15-6. The Shoe when powered with a good power plant, and propped correctly is an easy 105 mph plane. Out of a shallow dive at full throttle with the Shoestring, the speeds are insane. I would not want to do anythin like that with the RV, the tail is not strong enough for that, plus it would probaly take a healthy high revving 1.20 +++ 2 stroke to pull it that fast, the plane is not very streamlined at all.  The tail surfaces are flat, not even beveled at the trailing edges. 
Like I said before, the RV-4 will be a nice flying somewhat aerobtic scale type model, but by no means a High performnce model.
