Acer or Lenovo laptop?

The Acer is an Acer Swift. 13.3 inch very MacBook like solid state drive etcetera. Lenovo looks similar only it's a 15.6 inch, 1 terabyte hard drive same Pentium processor. Not looking to spend a lot of money at all.

I have had both brands.
Acer 2006 model Aspire 5610-4610 with Pentium Duo and Vista. Still runs great, quite capable for anything but fancy graphics games.
Lenovo 2011 model Fusion G555 with an AMD CPU and on motherboard GPU does Win7 okay. After 3 years the video chip detached from heating, a common problem, repairs failed. Put in new board, now used only with an external vent exhaust fan box.
Some other models might be better or worse nowadays.

Given a choice I would choose Lenovo each and every time they're just a much better laptop

When choosing between cheap garbage and cheap junk, just flip a coin.
