Gohan does better against gotenks buu than super buu does against gohan, so yeah the gap between gotenks buu and gohan is probably the smaller one. Just not by much.
In the manga, Gohan didn't do shit against Buutenks. Also, Buutenks stated he wanted to enjoy his fusion time as much as possible, so
he didn't try to end the fight fast. As for Gohan vs Super Buu, Gohan was pissed for what Buu had done, so, if that gap was the larger,
the fight would be over in seconds, unless you believe Gohan was fool enough to repeat the same mistake he had done against Perfect Cell,
dragging the fight.
