yes true its all personal preference, over here its mainly metrakit Pro Race that is used and they hold up very well, they are very reliable and easy to use, Hebo is similar so the same goes for them, Polini Evo is another good choice and the same applies to them, Malossi to me are tooo finicky the blocks require alot like ring gap adjustments etc and alot of the Team tuned blocks have been seized this season, BUT !!!! on the other hand not to be bias, they are powerful and have won our season THIS YEAR.
but like sed by trueOverrev at the end of the day it will be your decision . we all ahve our opinions and preferences.
