difference between solis inverters

[Guppy]

Can anyone advise the difference between the following Solis inverters

RHI-(3-6)K-48ES-5G and the S5-EH1P(3-6)K-L ​

I can see differences on the data sheets listed below but not really sure what they mean (is higher number always better) and just want the best inverter
Main differences I can see

Input DC PV side
Max short circuit current
RHI 17.2A v S5 -22.5A
Max. input current:
RHI 11A v S5 - 15 A

Output AC (Back Up)
Max. apparent output power:
RHI 6 kVA v S5 - 7kVA
Rated output current:
RHI 22.7A/ 22A. v S5 - 23 A / 22 A
THDv (@linear load):
RHI 2% v S5 <2%

Input AC (Grid side)​

Input voltage range:
RHI 184-264 v S5 187-265 V
Max. input current:
RHI 26.1A. v S5 - 34.5 A / 33 A

Output AC(Grid side)​

Max. apparent output power:
RHI 6 kVA v S5 6.6kVA
Max. output current:
RHI 26.1 A. v S5 30A

Efficiency
Max. efficiency:
RHI >97.5% v S5 >97.1%
EU efficiency:
RHI >96.8% v S5 >96.5

Everything else looks the same but the websites ive found it on the RHI is more expensive
All advice appreciated

One has a larger input power. 11A vs 15A

EHI is slightly more efficient, so I would guess that's the updated model.
