This was a game-changer for me - SO much better than the meat boiling in a sauce getting tough & dry.Make it myself because I find Chinese takeaway too sweet and Indian far too greasy.
However if you ever in Balham there is an Indian that gave up using ghee and loads of oil years ago and now wins awards all the time.
In terms of Indian spices I found something quite remarkable recently, an Indian shop that grinds its own spice mix and has been doing so for 40 years !!!

This is well worth a purchase. It's freshly ground (will have a label.with the grinding date) and is worlds away from the powders in the supermarket and unfortunately better than anything you could do at home. I have Tooting on my doorstep just about every spice going in the cupboard, but I can't replicate this. It's very special and the shop right in the centre of Liverpool is a local institution.
For a healthy alternative I roast whole onions (in their skins) followed by tomatoes and garlic, a bit of ginger and blend with stock to make a basic curry sauce.
Then it's just meat, fresh coriander and a couple of teaspoons of special blend.
Use as little oil as you like, for me it will no more than a couple of teaspoons. I religiously cook the meat before adding to the curry like the restaurants. Tends not to dry out. The exception being thighs.
I've not tried roasting whole onions, so I'll give it a go. Getting the onions cooked down properly is so important - I think it was Rick Stein (of all people) that got me to realise this.
I very rarely get a take away curry these days - we're out in the sticks, so it's a pain anyway, but being able to cook a non-greasy but very tasty curry makes the whole idea a bit redundant. I do miss having a full range of side dishes though (too much of a faff except for special occasions to make a load of them myself).
With regards to the original question, I agree with all those saying it depends where you're getting it / who's cooking it.
Curry just shades it for me.
