Depends on your needs.
I have both a nespresso and a breville dual boiler. I would say in terms of taste difference it’s very huge.

Nespresso is just for convenience, can make a cup in a min. But in terms of cost also higher than espresso machine.

Also recommend to just buy the machine from Lazada or Shopee official store. Because Rm3k credit for capsule is quite a lot, can buy more than 1000 capsules. Not too sure how much is your coffee consumption.
