- Motto: "Live 2 Die"
Go for Alternity, u can't go wrong. I've collected many types of TFs, Hasbro movie series, legends, deluxe, voyager, leader class, Takara MPs, Binaltech, etc. Now, most of them had either been sold off or thrown to my kids as toys, like those deluxe and voyager class. The only set I still keep is Alternity, and if u count them as well, will be all the Human Alliance voyager class from the movies by Takara.
Alternity is by far the one and only series that is systematic and logical, at least to me. A collection series should start with the leaders, which are OP and Meg, follow by the crowd favourites, like BB and SS. Binaltech is not bad, except the sequence of release is a mess (bots and cons release in random order), and IMO, too bulky and the robot form is not appealing enough to be consider a favourite. Alternity, on the other hand, has sleek design, the transformation is complicated but fascinating, and the alt mode is superb (I'm a car lover). To me, the interior of the car is important, it must have details. So I can't stand those deluxe and voyager class where the interior is filled with all the robot parts.
MPs are great as well, just that they are too exp. So, if you like sleek cars, modern looking robots, systematic series, nice paint job, great interior details, you can't go wrong with Alternity. Once you own the series, you will be like me, can't wait to get rid of all those deluxe, voyager classes, ugly plastic looking toys.
