Also consider what each dealer includes when saying they are "same price". Delivery, filling rear tires, first service, attachments at cost/discount, etc. All that has value too.
I don't think the Kioti is heavier unless the loaders are a lot different - but those 2 weigh close enough to call them "same". The LS has +2 PTO HP & 2 remotes. Kioti has larger fuel tank & better hyd flow. Lift capacities close enough to call same but the Kioti loader will lift it higher, faster, & smoother [maybe/subjective]. Going from memory & it's been a while but NX seat is better, easier to get on/off right side on Kioti (open station) but could on both. LS front tires about 10% larger diameter - don't know how that translates to ride smoothness on rough terrain but probably doesn't hurt.
In all, I would (and did) chose the NX between those 2.
Reality is they are very, very similar outside of the NX additional features like linked pedal.
