MPs and BTs.

Back when 20th anniversary Prime was released in 2004, we had no idea what it would start in terms of the MP line. Back then, Alternators and Binaltechs were also being released, and I collected them to go with the 1st MP figure, Optimus Prime. They kinda went together as far as scale, and the alt modes for Alternators and BTs were very realistic, even though robot mode suffered a bit because of it. But at the time, they were considered very detailed and top-of-the-line engineering, before the MP line blew up. Now, 12 years later, what are your thoughts on the comparisons between the 2 lines? Obviously, most if not all of us will say MPs are superior, due to their engineering being based on the animation models. So they're more accurate. But does that necessarily diminish the playability/collection value of the BTs/Alternators? Or do you still consider them a rather impressive addition to the toy-facet of the franchise, as well as your own collection, if you did collect the BTs/Alternators?
