Jets & Planes but no UAV's here.

The GRIPEN E/F would be a generational step up over the SUPER HORNET E/F in regards to stealth capabilities. It also would be cheaper to operate and to logistically to support and is considered one of the most overall reliable fighters in the world.

But as Don mentioned, there is that decades old issue of 1 versus 2 engines and the HORNET can carry a larger payload.

For most countries I think its the best option as they don't have the budget & its cheap to buy & operate. Means they might be able to fly them & maintain operational readiness.

Regarding extra stealth capabilities (excluding F-22) are they much use unless you are attacking or the enemy is low tech?
Stealthy from the front is not much use on a patrol because your presenting other facings.
My thought in this day & age every patrol is a data gathering exercise for the enemy eventually they will have a software update to track it once it turns head on as they will know what they are looking for.
