Honestly buy whatever you like the look of in terms of kite design and colour and also have a good hold of each of the bars and safety systems and choose which one you prefer and feel more comfortable with. Read up on the differences between hybrid c kites and bow kites because that is essentially the difference between the switchblades and the other two but as far as individual feel goes it is exactly that, individual feel and every single person will have a different opinion on each kite. In my experiences (haven't ridden the switch but iv ridden similar fuse/rebel ect) the switch will have a better low end, boost bigger and have better relaunch. The other two will drift better and be more forgiving while practicing unhooked (also make you look cooler

) but then again even the switchblade is looking more hybrid c than bow these days so I doubt there is too much difference.
All these kites a very user-friendly and fine for you to learn on, unless you buy a companies flagship beginner kite or wake style kite most lie somewhere between in terms of flight characteristics and all these days have top notch safety systems and enough depower to not kill you unless you do something completely wack. Both cabrinha and north are very top of the line build quality, anything anybody says beyond that is biased because they have owned a good one or the other or a bad one.. sometimes you get a dud regardless of brand and both companies/shops u buy from will be happy to fix most problems. Don't worry at all about the resell value, that is something pretty stupid to consider when buying a kite lol.
5 struts adds weight to a kite as a payoff for strength/rigidness for relaunch ability and canopy flutter ect. and 5 lines is considered a truer full depower (goes onto a single line attached to the nose) but can cause problems in the surf and complexity in having more strings..
EVERYTHING IS OF PERSONAL OPINION WITH KITES

just trying to cut through some of the BS.
