The artic telehandler have a wider cab and you can sort of side shift bales/pallets or whatever into and out of position and you have better visibilty to the sides, but are sat behind the boom. The do rock around at full steering lock . 

A standard 4 wheel steer telehandler is easier to jump on and off, which is more likely with this type of machine, you get much more lift and reach for a given wheel base. you can see the head tstock better, they tend not to rock around so much.

There are getting some really quite big ag spec telehandlers now, like this one https://www.fwi.co.uk/machinery/telehandlers/agritechnica-2023-173hp... Don't be tempted with a construction spec machine.

For the record, I've been using them since the late 1980's, JCB', Manitou's, Merlo's, Matbro's, a Teleshift off the top of my head. Rea wheel steer, 4 wheel steer and artic steer
