Front suspension coil springs: any difference?

[Funkyjazzlover]

Following on from this thread and a look underneath while on ramps (rear ABS sensor being replaced) my local friendly indy garage reckon the lean is probably a saggy front spring.

So I've been doing a hunt for new springs. I've bough Eibach springs for other vehicles in the past and know Sachs do a lot of higher-end OEM, but otherwise this is all new to me.

Short of spending a daft sum on boutique US springs, is there anything to choose between Lesjöfors, KYB, Kilen or Triscan? https://www.autodoc.co.uk/car-parts/coi ... omSearch=1

For context this is going on a L2H3 4x4 2015 with camper conversion, OEM suspension spec and running 30" dia tyres on aftermarket wheels with ET45 offset. I also plan to add in SumoSprings when funds allow.
