You can't go wrong with BRNO. Good dependable bits of kit. However, there's a lot to do with personal preference. Go to the shop and ask to see/try a whole bunch of rifles, even ones way over your budget. This will give you a good idea of what you like and don't like. Then they will be able to recommend a rifle that suits your needs and fits your budget. There's no point in setting your heart on a rifle that looks good on paper then you can't reach the safety catch in the field! Consider how you are going to mount a sling, if you want one.
I would suggest the Scope more important to get right. There are a few important things to consider:
First is the amount of light that comes through the scope, which will be a serious consideration in low light conditions. This can be tested by looking down the scope with your eye about a metre from the lens. You will see the image as a small bright area in the middle of darkness. The larger this area, the more light is coming through. Ideally you want this to be at least as big as the pupil in your eye, otherwise the scope is limiting the light reaching your eye. In reality, there will probably have to be a bit of a compromise. The amount of light is usually in proportion to the size of the objective lens, and you want at least 40mm, probably 50mm if you're in woodland or shooting in low light.
Second is the ability to adjust sights in the field. For this you probably want a large wheel to adjust the elevation, that you can use easily wearing a glove. A subsonic .22 will fall around 25 cm between 50 and 100m so it is important to get this right. You should also be able to adjust the zoom easily with a glove on.
Third, I would consider the picture when you look down the sight - the "reticule" or cross-hairs. This can come in various types and you can even get different ones in the same model of scope. Again, go to a shop and see which one you prefer. I don't recommend you get one with a dot in the middle - it obscures your target. Better to get one that has a box or ring around the centre of the sight that you can put your target in.
Top quality brands are Leupold, Zeiss, Swarovski.
Dependable cheaper brands are Simmons, Tasco, Bushnell, Nikko-Sterling.
There has always been rivalry between classic European brands and the clever modern Japanese, the same as Cameras.
I had a Simmons White Tail Classic, which was good but it wasn't easy to adjust elevation on my model. They run between 100 and 200 pounds so are affordable.
If you buy one with zoom, get one with "Parralax". This means it will stay in focus when you change zoom, and the "zero" should not change either. I don;t tend to find that zoom is all that important but again it's all about preference and technique.
EDIT: Scope mounts are very important. Don't buy cheap ones!
Hope that's useful. Happy shooting.
Oh, one more tip: When shooting, don't forget to BREATHE!
