Ahmed springs are very good, had these(borrowed) for a few weeks while avo coilovers were away for rebuild.
I would say it depends on what you want to do with the car, and suspension is a very personal thing, why not take your time and try to blag rides in cars with different set ups, would be my advice if you can.
Myself I found the ahmed very good but way too soft for me, had spax before as well as chassis dynamics(avo) std ride height and lowered on 3 door and cos std ride height chassis dynamics are excellent and I prefer these over ahmed.
My fave though is AVO, I like the ease of adjustability with coilovers(height wise) and avo seem my sort of damper.
I would seriously look at KONI adjustables with either ahmed or chassis dynamic springs for the road, just run koni on hardest setting, nice and comfy.
