depends. RAW usually allows you to recover up to 2 stops of lost light but the more you try to recover the more the photo is degraded.
You would need to test whether recovering detail in RAW degrades the photo more or less than upping your ISO to achieve the same shutter speed. Both will degrade the photo, do test shots with your camera to see which works best.
Try upping the exposure on any shot in your RAW software by a stop at a time to see what effect this has on photo quality to give you an idea.
Personally, I think to get the best quality overall you need get it right in camera. This may require the use of filters for things like bright skies rather than underexposing the land & then degrading it in recovery just to get the sky OK. I think the saying is 'expose for the land, filter for the sky'.
