I've been using ST2 for about a week now, and I'm seriously considering a purchase - even if the pricetag is somewhat steep for a text editor.
It's probably not going to replace Notepad++ as my system default text-editor (simply because NP++ starts at <500ms cold, whereas ST2 is ~2000ms, and I'm über-sensitive to these things) - but when starting some heavy-duty editing tasks? Yeah. It rocks. Package Control, multi-selections, fuzzy search, nice color themes and decent multi-language syntax highlighting, .... . . . . .
And while the pricetag is somewhat steep, I have a lot of respect for the no-noncense license terms. None of that bullshit "free lifetime upgrade" crap.
