Need help deciding...keep '09fx35 or upgrade to '16QX70; also suspension question

[doowopinfiniti]

I need help with making 2 decisions.
1. Keep my high mile '09 FX35 (219k miles) or upgrade to '16 QX70 (115k+ miles)?
2. Keep my H&R lowering springs/Megan Adjustable Control Arms setup or upgrade to BC Coilovers?

I picked up my '09 FX35 back in 2016 with 98k miles. The only mods I had installed were the Megan Adjustable Control Arms along with H&R Lowering springs and '09 GTR wheels. I had to replace the radiator and ABS module in the last couple years, but other than that, it's been pretty reliable. It now has 219k miles and it still runs great, however, I'm beginning to wonder whether now is a good time to get rid of it and upgrade to a newer ride. There's a '16 QX70 with 115k+ miles I have my eye on with the Premium and Sport pkg and although it has high miles, I'm very familiar with the FX35 issues and am confident it will hold up another 100K miles.
So I'm wondering what you guys suggest. What would you guys do?

To my 2nd question regarding the suspension setup, I love the ride comfort I get with the springs and adjustable control arms, but I do with it was lower. The concern I have with coilovers is the lifespan of the BC coilovers. Will they last more than a couple years? I read a thread in this forum where one user said one of the springs broke on his BC coilovers. I've had no issues with my lowering springs at all, so I'm wondering if anyone here has had the BC coilover setup for longer than 3 years and can speak to that. I prefer a lowered stance, but don't want any quality issues with coilovers.
So what would you guys do?

What did you end up doing?

I would keep the 09 and throw some cash at it. I would probably go all OEM for the best performance. I've tried it all (I had an 05 FX, then a 2010 FX, and now a 2017 QX70 S) so I can safely say OEM will out perform a lot of Aftermarket performance parts out there.

as far as suspension goes? Oem + Springs would go lower than coilovers?

Look into Silver's NeoMax coilovers. You can order custom spring rates, which is needed the lower you go to limit travel. I've dropped it about 2.5" and running 16k Swift springs front and rear. It's a heavy car. OEM + H&R springs is not that low, only about 1.5" drop from factory. My car handles way better than OEM or lowering springs. I have Megan adjustable arms front and rear as well, which are definitely needed to keep alignment in spec. It took awhile to dial it in, but I don't bottom out and nothing hits. Also depends upon the wheel and tire size you are running. I have two setups. Got 18x9.5" Enkei's paired with a 285/50 Continental and I have 20x9.5" Enkei's running Nitto 275/40 tires. More of a fender gap with the 20's as the tire size is only 28.7" in diameter. Stock tire size is around 31" I believe. So there are a few factors at play that need to be accounted for. Looking good AND handling well can be achieved, but there are limits. Due to the design of the front end, you can't go super low otherwise things start hitting. For me it was the width of the front tire, as anything wider than 265 starts to hit the fender edge as well.
