I suppose it depends on your current set up and if you need to justify the purchase (to yourself or the boss). I bought a Tacx Flux originally to train for an Ironman during winter. I had a carbon Trek Madone at the time and didn't like watching the frame sway beneath me during hard efforts. My weight fluctuates a bit depending on my activities and how much weight training I am doing so between 83 and 90kg and I can push out 1,100w in a sprint and felt the stress may damage the frame. Bought a cheap and poorly maintained Giant alloy bike which was noisy and poorly geared, tbh I could have done something about it but did little other than lube it from time to time, the drivetrain would rust easily due to excess sweat and got a bit messy. A lot of the other exposed areas were rusting too. Bought the Neo in BF sales a few years back.
For me it is quieter, maintenance free, easily adjustable through 4 settings which are numbered meaning we can switch between myself and my mrs very quickly, is super stable under the hardest of efforts, has a little tray for your phone and the remote, built in ipad stand plus 2 x USB charging points, better freewheeling, smoother and sharper gear changes (quicker than my Di2 Ultegra road bike). Only has a single cable although unless you are wanting to charge something then you don't even need it. Above all though its just more appealing. I've done almost 11,000 km on Zwift and 7,500 of that has been since I have had the Neo of which I have had for around 50% of my time as a Zwift member so I think that shows. Having said that for the best part of the last year I have been self employed so finding the time to use it has been easier.
It looks cool too
