I dont know, it all depends on your mood. Like for a while I was all about bombs, now Im just in the mood to piece. And when I started I was all about tags. It just depends on were you are in your mood.
I like both for different reasons. Tags are fast for territory. Throw-ups take a little while longer, but are maybe more aesthetically pleasing, and pieces are my favorite, but can be tedious, and definitely not for covering a lot of ground at once. ACtually I just wanted to make the longest run-on sentence I could think of.
Probably right now I'm working mainly on doing tags and throws, however I usually sketch all my peices and do my peices legally somewhere.
i could do all but i mostly do taggs and throws cuz they're fast to do for those on-the-run occasions.
I like em all mostly because the pigs where I live don't really give a shit whare u put up as long as u don't do it in public or somewhare nice
