Prison Break is A LOT better I think, Season 1&2 were amazing, 3 was good but it wasn't really needed and 4 was just quite bad.
Breaking bad I found to be quite slow an boring apart from about 3-4 moments, I expected so much more after all the hype it got. Also Marie and Skylar were just so annoying and over the top about everything. Watch the first few episodes of prison break and you will most probably get hooked.
