Yes, but not necessarily *best* glide ratio - which is almost meaningless.

A Pegasus 101A has a best glide of 41:1 and can be had for about
US$25000. An LS6-b has a best glide of 40:1 and can be had for about
US$40000. So, why pay another $15000 for a glider with the same best
glide? One reason is what happens when you go fast (and, in general,
nobody flies XC at best glide speed). At 80 knots (about 150 km/h). The
Pegasus glide ratio is down to 22:1 while the LS6-b does 29:1 at that speed.

I've owned both of these gliders, the Peg in a partnership. :-)
