Anyone Had A '16-'21 Euro4 And Upgraded To The '21+ Euro5 Model?

Just wondering if there is a very real world ride difference between them?

Do the alloy wheels feel different?

Do the lighter internal engine mods make a discernable difference to acceleration?

Is the weight reduction noticeable?

I'm considering a T120 and would appreciate your thoughts about whether it is worth spending extra ££'s on the 2021 up models? (loving the cobalt blue/ice silver paint job).
