First of all if your goal is to play poker for profit and make you bankroll grow, then you need to understand, what bankroll management means. And when you ask about satellites, that makes me think, you probably dont, because satellites dont have any place in the schedule for someone playing with a small bankroll like 200£.
So do yourself a favour and read some articles or watch some videos about bankroll management. There is free material here on CC and several free videos on Youtube from people like Bencb, Felix, Jonathan Little and others. I am not going to make this reply another tutorial about bankroll management, but with 200£ you can basically play the following games on PokerStars:
* 2-5NL cash (30-40 BI or more)
* Single table SnGs up to 3,5$ (50-70 BI or more)
* Multi table SnGs up to 2,5$ (70-100 BI or more)
* Small field MTTs up to 2,2$ (100 BI or more)
* Large field MTTs up to 1,1$ (200 BI or more)
I have never played on GG Poker, so I dont know, if the cash games there are good. But I know, PokerStars have lower rake for 2-5NL cash, and those games are certainly beatable, so I dont see any big need for an alternative. If you want to go the tournament route, then a big drawback of GG Poker is, they dont have SnGs, and most of their MTTs are fairly large.
This is problematic from a bankroll building perspective, because it increase variance and makes it difficult to get volume and practice. So I would highly recommend starting at PokerStars, if you want to focus on tournaments. And maybe its then worth giving GG Poker a try, when you have 500$, so that you can play small field MTTs with up to 4,4$ buyin and large field MTTs with up to 2,2$ buyin.
As for playing without a HUD on PokerStars I have never tried it, but I am pretty sure, its possible to beat all those games, I listed, without using a HUD. I will also say, that HUDs tend to be less usefull in any kind of tournaments, because the player pools are so large, and because stats are affected by varying stack sizes and number of players.
I always have my HUD running, but its actually pretty rare, that I use it to make big adjustments. As Axmanace say, a HUD makes it easier to identify the fish, but especially if you only play 1-2 tables at a time, manual observations can also go a long way. Lets say you open AJo for 3BB in the first hand of a SnG, and the player to your left now jam his 75BB in the middle for an absurd overbet. You fold, and so do everyone else, and next hand he open limps. Do you need a HUD to tell you, that this player is a fish?
Also I will say, that while it obviously makes no sense to spend half of your 200£ of software, if that is all, you have to work with now, in the long run you are going to need to make some investments in order to play poker for profit. And a tracker should probably still be the first piece of software, you invest in. So maybe consider doing this, when you have grown it to 400-500£.
