Have never flown the Citation, sorry.
The CL30 is a very strong performer and will be happy on 1500m-runways with a full load out and 1200m in. It will also take you straight to FL430 @ M.79 at MTOM, so if airspace structure is a concern, this capability will generally buy you a direct or two.
Baggage space depends very heavily on what galley has been fitted, so worth checking out before buying - the Citation might well come out on top here.
Range is the biggest advantage for the CL30. 3100 NAM with ample reserves, although it will only lift 2 people and their modest luggage with that kind of fuel on board. Make sure your aircraft has the increased gross weight mod - or you're down to 1 punter and his briefcase for full fuel.
Technically well designed aeroplane - the jackscrew lube system on the flaps is known to need a mod, so that should have been done before buying. HYD press sensor on L system known to suffer failures due to vibration where it is installed, but apart from those two minors, no real worries. Spurious failures of various sub-systems are not uncommon, but that's true for most modern small aircraft that have a lot of computers.
Cabin space should exceed that of the Citation, and they've been strong sellers from word go, so resale value should keep up (or should I say recover?).
If you told us your typical mission profile and the next two subsets, someone in there might give you a better comparison - or suggest other types worth considering. My money is on it being down to cabin space vs. range.
