I have been using both systems, including WiFi through the MTH app on an android phone, on my test layout over the last couple of years. Over two years ago I wrote the following, and I have not changed my opinion.
"... My recommendation is not to limit yourself to one system: plan to buy both at some point. I have both and I like them both. I run Legacy engines with my Legacy remote, not through the DCS system, which works well for me. I do this mainly because I like the Legacy remote better than the DCS one, plus I really like Legacy's quilling whistle. If you already have a layout I'd go with Legacy first because of its easy setup. If you want to try command control with the least investment, you can buy an older TMCC Cab1 and base pretty cheap to run TMCC engines (which can be found fairly cheap too) and Legacy engines in TMCC mode. No matter what you do, you will really like command control." My only addition is, after using the MTH app to control both systems, I still prefer the cab2 for my TMCC/Legacy engines.
