I do like Sun Vulcan Robo. Like DaiDenjin, the combined form is far different (from the Jet at least). I agree that the manner in which Cosmo Vulcan moves its parts around helps reveal exactly how such a transformation works. Bull Vulcan are just legs with treads and aren't that impressive. In the first episode (at least), Cosmo fired shots and Bull could either latch onto or batter and throw the Monger. Sun Vulcan Robo is one of those "less-is-more" Sentai Robos cause it has an array of weapons and techniques. The "Aurora Plasma Dash" finisher has several variations: horizontal, vertical, and a combination of the two sets (of stock footage). The "Aurora" is also crucial in the final battle, but I won't say much on that here. I do think that Sun Vulcan designs were copied years later for Gingaman.

Goggle Robo is the first where "Five-Rangers-use-Three-Vehicles" to combine. The effect is...acceptable, but that's about it. Goggle Robo is the one you can't find reasons to hate or love; it's just...there. It's not a useless Mecha, but you can see its "blocky-ness". It was Zyuohger before Zyuohger! The Goggle Ceaser literally kept the Three in block-like containers which could roll-out on their own! It's finisher is redeemable for its preparation visuals. What I haven't seen is the final battle where they use a different finisher against the boss.
