I have been using digitrax since 2000 year, and swap to Lenz in 2005, I also have tried Digikeijs, Z21 (white box), CS2 (marklin but used as DCC) and Uhlenbrock Intellibox for more than a year, after testing all of these I still prefer Lenz, the reason are: bulletproof quality, fantastic reliability, no need of continuous updating due to incompatibilities or bugs, and very simple to use. And if you need fancy functions (like locomotive icons, automatic operation, layout schemes, etc.) you just have to add a computer and a software, and you will have all for much less money. If I would be obliged to change I will select Intellibox, specially because you can go fully automatic operation without the need of a PC, nevertheless user manuals are rubbish and learning curve is way longer than lenz. My advice, stay with Lenz.
