More wheels than sense
What differences are you expecting ? And how many grams are you going to save ?

Flip a coin. Heads you're going to waste your money. Tails you will blow your money.

Don't bother.

Another vote for not bothering unless the triple is knackered and you need a new crank, you'll only save the weight of a sandwich.

So you're looking to save (maybe) 200grams on a trike weighing (maybe) 20 kilos? My advice is don't bother.

The Chainsets my last change i need to make, as i've been updating my Trike over the last couple of years. I never use the granny chainring(one of the advantages of living in North Norfolk). I was just wondering really if the Sram Rival would be a better choice than the shimano 105.

You've wondered, we've answered. Go for a ride. Your location is irrelevant.

Ive used both systems & have found that chain replacement was necessary approx 500 miles sooner with the SRAM

If you don't use the granny ring and really feel the weight loss would be useful in some way then remove the granny ring and mounting bolts.
I did the opposite on my MTB tourer - never ever got on the big ring when fully laden, so off it came, although it's made zero point zero zero zero difference to the ride or performance.

Mileage on 'most used' bike between December 2014 & December 2015 was a fraction over 6200 miles. The chain was replaced 4 times in that period due to wear/stretching. SRAM Rival fitted.
Replacement 'most used' bike fitted with Shimano 105... mileage between February 2016 & June 2017 is 8500 miles. I have just replaced 4th chain less than 50 miles ago.
Factual evidence from my riding. If have have any evidence which substantiates your nonsense claim, I'm happy to agree to disagree on the matter.

OK, since you applied such rigorous scientific method, please give me a list of the exact length of each chain over a 24 (half) link section at the time of replacement.

My method was not scientific, however, I come from an engineering background. Chains were checked using a chain checking tool replaced when necessary (in excess of 0.6% stretch). Pins were also measured and replaced when worn beyond 0.25mm (tolerance when new never exceeded +/- 0.03mm for either make).
I will say that the last chain used on the SRAM Rival set-up was a Shimano105 (all my LBS had in stock). This was still going strong after 1500 miles.
I look forward to your counter argument which confirms your nonsense theory.
