Which lens??? RF28-70mm vs RF24-70mm

Is the Canon RF28-70mm F2.8 is STM a good budget friendly equivalent (or close equivalent) to the Canon RF24-70mm F2.8 L is USM Lens?

Yes that is exactly what the RF 28-70mm F2.8 IS STM lens is, a great budget version of the RF 24-70mm F2.8L IS USM.

You lose a little at the wide-angle end, you get the smoother STM focus motor that is slightly less snappy at switching focus than the USM motor in the L-series lens, you also save weight and money. You also miss out on the weather sealing of the L-series lens. 

Probably for most general photography the biggest difference is the field of view difference between 24mm and 28mm especially if you are in a location where you cannot move further back to get more in.

p4pictures nailed it, the RF 28-70mm F2.8 IS STM @ $1000 is a very nice budget friendly lens. If you don't need the speed of a f2.8 another option is the RF24-240mm F4-6.3 IS USM which is $900. If image quality in also very nice, you will pick up a slight gain in the field of view over the RF 28-70mm F2.8 but will compromise the speed of the lens. If you don't shoot a lot of low light it may be an option. This was an early morning, overcast shot on an R6 MkII

I would say what are your goals? Are you a hobbyists or a looking as a professional? Hobbyists, yes, but pro maybe not as good of a choice. 4 may sound like a small number and it is but when comparing FL at the short end of a lens 4mm is quite a large number. Plus there is build quality. A day in day out has to be there lens is a different consideration.
