After testing I fully agree with this compromise. Below are the 
latencies I reached with no xruns during a 10min rakarrack session on my 
test laptop (Dell Vostro V13 with a TI firewire card):
-generic: 16ms
-lowlatency: 4ms (@2ms: tons of xruns)
-realtime: 4ms (@2ms: many xruns)

To put it simply: -lowlatency all the way! It delivers impressive 
results for maintenance requirements way lower than -realtime (or -rt 
even more), meaning less work for maintainers and new kernel candy for 
users.
A few diehard performance fans may appreciate a PPA with -rt, but if 
there must be one sustainable and supported priority, it is -lowlatency.

Exciting times!
