What MacBook should I get?

I'd recommend a MacBook Air with a 15-inch screen, and at least 16GB of Unified Memory.

Apple is expected to release new models with the M4 chip quite soon, which will be faster and also bring down the price of the M3 Airs. The M3 models are still a great option and will be plenty speedy for your uses.

Are you planning on using two external displays? If so, that might be a reason to go with a Mac notebook that has a Pro chip, a Max chip, or a plain M4 chip over one that has a plain M1, M2, or M3 chip.

The M2 MacBook Air can only drive one external display. The M3 MacBook Airs can drive two external displays, but only when their lids are closed.

I’m not sure if I’d like a PC or laptop but don’t really know the differences between them.

PC = Personal Computer. Many people use the term to refer to computers with Intel or AMD processors that are running Microsoft Windows, although strictly speaking a Mac is a personal computer.

Windows PCs and Macs are different platforms – and software built for one is not compatible with the other. You can get Microsoft Word both for Windows PCs and for Macs – but that is because Microsoft has built versions of Word both for Windows and for macOS. If you bought a Windows PC, you'd need to install the Windows version; and if you bought a Mac, you'd need to install the Mac version.

A laptop is a portable computer that can operate off battery power. A laptop could be a Windows laptop, a Mac laptop, or something else (like a ChromeBook).
