Mecha rpg : Apocalypse frame vs beam saber (vs lancer (vs mekton Z) ) ?

Hi Folks, I took itch Games for Gaza bundle. Among the games in the bundle, I’ve seen 2 mecha games, Apocalypse frame and Beam saber, I believe the first one is a PTBA and the second a FITD, I have no opinon on these “system family”, it’s vague enough that it can lead to a good or bad game....
