Default Springs vs coilovers?

So I already have swift springs waiting to get installed. A good friend of mine who knows his **** told me I'm making a mistake and should do coilovers. Told me springs will damage /blow struts. My previous car (Altima coupe) , I had springs and blew a strut. Friend told me if I want the cheap route to keep springs but get struts that are dampened for that spring rate... any insight? Looking for someone to educate me on this subject.

Correct unless you put higher spring rates than stock springs (the shocks don't have to work as hard). Shock valving needs to be matched properly to the shock compression/rebound (spring rates) of the spring. Mismatch results in premature failure of the shocks.

A member on this board blew his front two shocks in his RCF after he had installed RSR super downs. Those springs have much softer spring rates than stock so the shocks have to work extra hard to control the movement of the springs. It results in shocks giving out earlier.

To my knowledge, this is all moot though if we're talking about '17+ RC-F's due to the AVS.
I've heard some cars switched springs, but I haven't heard/seen anyone with full coilover change or even air yet.
On that last part I may be wrong since it's been a minute since I checked.

SO aftermarket shocks are recommended? Does bilstein make any?

Yes, aftermarket shocks would be better if you want to go with lowering springs. Check with these guys as it looks like these work with RCF (as they are for ISF)

I'm regretting buying the springs. Should have saved up for coilovers, but I don't wanna spend any serious $$$ until car is paid off. Figured springs were cheap solution for now, too late to return them so just trying to make it work.

Swift Springs are designed to work with OEM or Aftermarket Shocks

"Every Swift Spring is prototyped on OEM vehicles to ensure the highest level of performance. By working around the OEM dampers, it ensure that every spring will work for a daily driver or a weekend track driver."

This was posted on swifts website .. reading this leads me to think stock shocks would be fine? I know a few members had issues with the rsr springs. Havnt heard issued with swift though unless anyone can chime in?

You can try doing it and see how it goes. If the shocks leak oil then you can swap them at that time with Bilsteins. Swift are definitely better than RSR super downs (in my opinion, which are garbage) in terms of spring rates and match the stock shock/struts better. Not sure if the ride will be bouncy or not . You will have to get an alignment to try and restore the camber/castor/toe as it changes when the car is lowered 1 inch or more.
