Got my macbook used it for 3-4 days did not like it at all. I found the mac OS much harder to use and it took me 4-5x longer to do things. Also all the programs i used seemed slightly watered down versions compared to windows. I could not even figure out how to uninstall programs fully it would always leave extra files, where windows there is an uninstall button and manger. Luckly apple allows you to return stuff 14 days after free so can do that and not have wasted my money.
I have to draw back far for this, but give it a try (and sorry for my non-native-english):
I grew up with DOS/Win3.11 and used all the Windows-versions up to Vista. I was a really annoying Apple hater and didn't got used to linux or anything else than Windows. 8 years ago, I started to work for a TV-Company, where all the workflows were based on Macs. So I was faced to work with Macs. I wasn't pleased at all, but i also wanted the job. So the first week it felt like my hands were bound, the whole OS felt like some bricks of Lego-Duplo after playing a long time with Lego-Technics. After two weeks it was getting better. I started to understand, how apple hides all the tech but leaves it accessible, i started to understand the workflow and the benefits of the system. It lasted at least 2 months until I came to a point where it wasn't completely unreal to use OSX also in my private environment.
And you know what? Today, I use Apple-products at most. (Right now, I just have the retina-Macbook as my main computer combined with a NAS and a mac-mini as a server at home)
Don't get me wrong, if OSX isn't your thing, you leave it anyway and use what feels right for you! I have no interest to convince you. But you are the one who made the step to buy a Mac, so now give it a realistic chance, use it as long as possible, be open for new workflows, your new mac can do all the things you want to do! Sometimes different? Yes! Mostly faster? Yes!
One example how different a workflow can be, you just wrote by yourself: How to uninstall programs on a Mac? Short answer: Just throw it in the recycle bin!
But you might ask yourself: What about all the data the app threw in the system?
Right here you have to think different: Unlike in windows, in OSX the apps don't spread over the whole system, they're not allowed to, they just sit in the programs-folder. IF you have to "Install" a program on osx, there will be an uninstaller too, right in the apps folder. - No Manager needed -
But to be honest, of course there will be leftovers: App-Data, like game-saves, fonts or sometimes some settings-files will be left in some library-folders in the system. But you know what? in Windows, most of these data (and a lot of different waste) will also stay in the system, an uninstaller isn't that clean as you might think ;-)
Because this is a problem of all operating systems, i use an App called AppCleaner (just google it, it's a free app), to perform a clean(er) deletion of my apps, just to be sure ;-)
Anyway you'll see, unlike in Windows, there are not much files connected to the app at all.
Long story short:
Just stay open and give OSX a real try as long as possible before you decide, no matter how you decide.
Peace ;-)
