endless threads, blogs and videos have been dedicated to the hi point 995TS.
don't compare the 995TS and the CX4 storm. the only thing they have in common is being blowback 9mm. from there it's apples and oranges. personally i think the 995TS at $300 is overpriced. on the contrary, the beretta storm is worth the $800 price tag.
if you think $300 is such a great deal for a POS like the 995TS, then checkout a marlin model 60 or 795. there's a top notch 22lr semi auto rifle for well under $200. to me that is a good value. so no I would consider the 995TS to be at least $100 overpriced.
the 995TS is heavy and the mags are crappy. the feed lips bend easily. the optics mounting options are a joke. the rail is made of gummy bear plastic. that being said the gun does function fine and can be fun at the range.
on the contrary the CX4 storm is high quality polymer with all sorts of clever design built into it. it uses 92 mags which in ban states like MA are a great option. the gun is 100% reliable on pretty much all ammo. the CX4 is also very lightweight with great sling mounting options. my only beef with the CX4 is the thumbhole-ish stock design which makes reaching the mag release difficult. otherwise the gun is near perfect.
if you're looking for a quality pistol carbine or something used for HD get the CX4 storm. if you're just looking for a beater that can fling 9mm then get the 995TS.
