I think the oil consumption issues were rectified on the later engines. The GM transmission has its issues, but as mentioned above, fixable. Isuzus and Monteros in the models you are inquiring about are similar suspension wise. I would suggest driving good examples of both and see what feels good to you. I will say here in Southern California there are more Monteros than Troopers. Can't say if that reflects sales or reliability.
