I've heard ATPs do both.
I was at Orlando Exec, and was given a taxi instruction:
F K A, cross 31, A2 hold short 25
and read it back as
F K A, clear to cross 31, A2, hold short 25
The ground controller blasted me, "you haven't been cleared for anything", wanted to talk to my instructor, which I responded I was solo pilot, then he ranted on and on...
At which point a lear jet pilot cut in "if you are finished, we like to get our clearance", which knock the controller back on his heels and I eventually read it again and this time I didn't use the "clear to"
My CPI said that my read back was fine, we use that at my home airport, it's the only time I've heard a controller yell at someone, and hopefully the last time it happens to me
