That's a bit rude, dude. We definitely cannot tell you whether to go for a PCC or not. Consider this:
1. IRCC needs a PCC that has a 6 months validity.
2. Do you know what CRS score you're going to get after IELTS/ECA?
3. In USA, you'll be able to get PCC within 6 days, but there's also a 90 day wait through another route. Not very well versed with this but do a little research and you'll get the info.
You haven't specified what CRS you're likely to get, so base your decision on that. You need PCC only post ITA.
