Nike Vomero 18 vs 17

Hi!

So I'm looking to get my first pair of proper running shoes. The Vomero 17 and 18 seem to have the best reviews. The Nike Vomero 17's are around £85 at the moment, whilst the Vomero 18's are around £135. Considering they both have very good reviews, are the Vomero 18's worth the extra £50?

Thanks!
