I have experience with both Battery Tender and CTEK.
Mercedes / AMG uses a rebranded CTEK charger. Same with Ferrari and Lamborghini, I believe.
The CTEK is much more high tech and can deal with a wider variety of batteries and battery states (i.e., it can recondition and recover dead batteries).
Both are pretty solid. I do trust CTEK more for higher end cars, however.
