I reckon you would be alright with that one mate the tab 2 10.1 for me was a little sluggish but ive heard they have improved alot with the 3 but its funny as i found the note 2 7" really Nice dunno if it was diffrence in screen size i really don't know.
Have you uninstalled all the bloatware? You might try running custom roms on your tab which might improve the sluggish perfomance
