Depends if your looking for realism. Like CDN_Stalker said, they are reliable, but then again, it's not like hi-caps break every week, you'll get your good use out of either. Midcaps swirl around inside the mag, and the spring has to swirl with the BB tube. Hi-caps come in 300rd and 190rd 20rd styles. The 300rd is fine, pretty cheap at around $12USD at ebaybanned or redwolf or something to $18 at VA, but yeah, they rattle like mad. The 190rd is a pain in the ass, since you need to wind it up about every 15 BBs
