I made this graphic back when people were people were complaining about the look of MP Ironhide.
This is what toy designers are trying to emulate...

Only one small portion of the vehicle mode - the front - remains visible in robot mode. The rest of the vehicle
disappears into thin freakin' air in robot mode. In reality mass cannot be created or destroyed (re:
Law of Conservation of Mass-Energy). This is why fans came up with the idea of mass-shifting in TF fiction to explain how Transformers can change sizes between transformations (e.g. Megatron, Soundwave, Reflector etc.) - mass is displaced, but not generated nor eradicated.
So this means that IRL all this mass
must go somewhere in robot mode. Your two options are:
1. Make the excess mass detachable. This is what the G1 and Timelines toys did. A good bulk of the vehicle was detachable and transformed into mobile platforms.
2. Incorporate the excess mass into the robot mode - self contain it. This is what CHUGUR and MP Ratchethide have done. Obviously the MPs have achieved it at a greater level, but of course they are newer toys, larger toys and also $100 dearer.
I still challenge anyone to show me any other toy, aside from MPs, who have been able to achieve this marvel of engineering as CHUGUR Ratchethide. Because comparing them with many other toys isn't necessarily fair because those toys aren't trying to achieve the same thing that CHUGUR Ratchethide have achieved.
Fair point, but it's a trade-off for having these toys self-contain all of their vehicle parts. At only a Deluxe size and budget/price point, you're not going to be able to make the vehicle modes look as smooth as the MPs. The alternative is to make half the vehicle detach, in which case you might as well stick with FunPub/Timelines Ratchethide. I own Timelines Ironhide BTW and I much prefer the Henkei toy.
That's subjective. I like the face sculpts, but it's a matter of personal taste. I don't think it's inherently bad though. The downward facing heads do bug me - someone at HasTak had a thing for it at the time. Universe Silverbolt suffered from the same thing too... weird.
Again, physics.
Yeah. I'll grant that this could've been done better. Mine don't seem to be as problematic as others, but I must admit that they're not perfectly solid either.
Again, I'm not saying that these are perfect toys - they do have their flaws. But I still think that, considering the craziness of what they were trying to achieve, they are still FANTASTIC toys. Even if you think that they've been completely outclassed by their MP counterparts, I still really like them because I judge toys by the standards of their day, not by standards of their future. Because if I were to judge all toys by today's standards, then G1 is utter rubbish.
Another question I may pose is - how else would you have expected HasTak to have engineered this mould? Physical flaws like creating a tighter mushroom peg, having the heads face forwards etc. - okay, totally fair calls. But I don't see how they could've avoided other things like the backpack kibble or the seams on the sides of the vehicles (not without making them shellformers). Even MP Ratchethide still have some visible kibble on the robot mode, e.g. hip panels, bum wheels etc. - it's just not possible to completely conceal everything (at least, not unless you wanna pay $300 per figure).
