In case your ultimate aim is to practise in India, NEET-PG is the best and the cheapest option available. Unlike with the western exams, USMLE, PLAB, AMC, MCCEE, etc., at least there is a certainty with NEET-PG that if you clear the exam, you will get a seat depending on your rank.
The PLAB route is for someone who plans to settle in the UK or at least has a proclivity for the UK, if not surety. You may read more on the PLAB route here, What is the major difference between MRCP and PLAB?
Lastly, PLAB may look comparatively easy, however, the process is equally difficult, tedious and competitive. It may take 8–10 years to become a specialist in the UK. To practise in India, you need to learn the art of practising medicine in India and by clearing NEET-PG, you can be a specialist as early as in 3 years.
