Does it matter at all whether you start out with lynx or rhino other than the first two free armor pieces?

[Donald J. Trump]

Topic says it all, are there any difference between the two startout options besides the two vouchers you get?

It doesn't matter at all.

You'll end up with one arm piece and one leg piece + those schematics for the same... which you will naturally gain early on regardless.

As Neuro said, it only controls 1 arm part and 1 leg part that you receive when you reach the first "health station". In terms of accessibility, you should get all Lynx part in the following couple of guys if you specifically aim for their pieces of hardware (yellow/defended zones) and end each fight with a finishing move. (In that case, I suggest you take a medium speed & damage weapon as they do stun enemies fast enough and also deal enough damage to avoid counters.)

For the Rhino set (and remaining pieces if you selected it), it's in the same first big area, but you got to unlock some shortcuts in the zone first to actually make use of the enemies' respawn feature to easily get all Rhino's pieces.

Take notice that some enemies don't respawn and might have to be met further down the road as regular enemies before you get a chance to try again to take their piece. But when you meet them for the first time (which usually seems like a small boss as they are different from most other enemies around), you should aim for what you really want on them (most of the time is their weapon... which usually also gives their arm schematics).

For example, you'll meet a guy with an huge kind of hammer/axe locked in a room which will deal massive amount of damage on you. If you die, he will still be around that area where you fought him... but if you kill him, he doesn't respawn anymore.

By the end of the first area, you will have access mostly to 2 full set of armor/frames, at least 6 weapons (if you collected them all) and a huge bunch of different implants all rank I.
