I am scanning my color negative film am I came across some posts suggesting TIFF format because it is lossless.

My question is, if both fornat are of 24 bit (8 bit channel)

Wouldn't the quality be same ?

If I want to edit JPEG losslessly, I can always convert it to TIFF and can edit as much as I want without loosing any quality.

Any time you edit the numbers (and that's all digital images are), you can introduce rounding errors. Depending on the edit and the bit depth, this can cause banding of your images. JPEG only supports 8-bits per color and while fine for a final output format, it's not fine for image editing. That's why people are recommending 'high bit' data (more than 8-bits per color). Now that could be 10-12-14 and very rarely true 16-bits of data but the point is, you have more than enough data to overcome any rounding errors in edits that can 'damage' the quality of your data. So, high bit, (and I'd suggest wide gamut), TIFF. Then after editing, spin off a JPEG for when you need that format.

So there isnt any point of scanning in TIFF and utilising TON of space necessarily.

Yes!
