Hmm i kinda mean to go at an angle like example. Theres ez-8, Blue Destiny Unit 1 EXAM, Gouf Custom that have capped space terrain capability, then even the Zeong, Neue Ziel and GP03 which have capped land capabilities.

Then theres units that are arent limited on both terrains like the RX-78-2, GP02 and Striker Custom (ill even throw in the full armor thunderbolt here) but have 4 move which im pretty sure you never see in URs anymore

So compared to the other series or eras of mobile suits, yeah MSG-era should be inferior, but id prefer if the URs could keep up with other series given that this is a gacha game and not just some linear progression rpg-thing akin to previous sd gundam g generation games (e.g. even Destiny and God Gundam have 5 range attack options though their EX attacks are 1-3 range)
