i dont have alot of experience with many different kinds of controls, however i have used a few. i have an x-arcade unit that gutted and used in my own panel...i wouldn't reccomend doing that. my friend has an ipac4 with happ competition sticks and happ buttons, as well as an ultimarc Jstick for 4way games. his controls all feel great, and the ipac was easy to work wih.
i recently placed an order with divemaster for two u360 sticks and a bunch of happ buttons....that was on the 31st, so I dont have them yet to post an opinion of them, but from what i have read, you cant beat them.. yeah a few people have had some minor problems, but from what i have read, Ultimarc provides customer service that is above and beyond what most companies do.
as for the magsticks...do some searching, just about everyone here who has bought magstiks says that they are stiff with a short throw, and while it is nice to have a switchable stick...i beleive most of them have since bought something else.
perhaps they will work well for you, but i suggest you do some looking around. read reviews and make an educated purchase. i have been debating on what to buy to replace my x-arcade for nearly 2 years now...i think i made the right choice with the u360s..i guess i'll find out soon enough.
i have done alot of research on these sticks, and i havent found any cases where someone regretted buying them...i can't say the same for the magstik
