I hate to admit I didn't remember strawberry wood was an actual variety of briar; I like that it is notably light weight. The other wood that I know that works well is Mountain Laurel, but it is fairly rarely used. It was popular during World War II when briar producing areas were in the war zones. A carver in N.C., Jerry Perry, carves some in Mountain Laurel, and I have one of his pipes, a small freehand, that was done in Cocobolo, though Cocobolo can be a problem to carvers in that its sawdust can sensitize respiratory tract tissue. After WWII, when briar again became available, many U.S. made pipes were stamped "Imported Briar," to emphasize that it was again available, and it was preferred and a good selling point.
