They both seem like fairly good options, if you're experienced with their playstyles.
The first one has a huge number of vehicles that all start in play, and an ungodly amount of shooting, so it gets a tick for target and threat saturation. It does have a marked weakness to air, as you mention. You can play around this, but if you ever draw a card asking you to kill an aircraft, you're going to hate the lack of aircraft yourself.
The second one is more finicky, because asides from Dissies, the main anti-infantry capabilities come in turn 2 at the earliest, have no reserves manipulation, and are only One-Shot missiles. The platforms they're on also want to shoot at other aircraft, so their focus is going to be split a lot. It is probably a lot more balanced, but lacks the single-minded focus and raw instant dakka the first list has.
Perhaps consider a mix of the two - a list in which you include one or both Razorwings, but then switch out some of your Raiders carrying Kabalites for Venoms.
Overall, I think your current two lists are both very strong. Just giving some food for thought!
