Basically you can spend as much as you want on any number of variations of technical solutions - but my input for what it is worth is that I prefer to use a wrist mounted computer for depth and time, but I use it as a backup for no deco limits and safety stops etc.
The Air Integrated (tank sender) on my wrist computer failed after 30 or 40 dives, and hasn't worked since so personally I don't trust AI with a sender for air, but that is just my personal experience. I also have a console computer which is air integrated (i.e. attached to the tank via an hp hose) which is what I use for gas and deco/safety stops. I don't have an analogue depth gauge because the one I first bought was very slow to react and inaccurate so I ditched it pretty quickly. In side mount I dive the wrist computer for depth and dive times and NDL, and use two Hollis brass pressure gauges on the first stages (one each tank).
So basically in your position I would be inclined to go for an analogue pressure gauge on an HP hose for pressure, and use a wrist computer for depth, dive time, NDL's and safety stop times etc.
I won't mention the make - it is irrelevant here, but I have regularly had problems with transmitters on air integrated computer but have never had problems with the depth, dive time and so on with them. Whilst you are looking at consoles I would also suggest you steer away from getting a console with a compass in it as well, I have never had much success with holding it far enough away from me to see it properly (my age) or to line it up and navigate with it, so you may want to think of a separate compass, either wrist mounted or on an extender (which is what I use).
But at the end of the day it comes down to personal choice, and you need to find what works for you - dive safe and have fun - Phil
