Hi OP. I'm a first time mum as well. I found the electric pumps personally bloody useless and have had much better luck with a manual pump. However, I pump milk into the bottle that came with it and pour it into separate containers, it doesn't matter which brand
I am currently feeding my ds (dc2) with mainly breast milk from a bottle, plus some breast feeds and formula top ups. So, I pump rather a lot! If you are planning to pump a lot, then I would say a hospital grade, double pump is the best thing. You can hire a really good version directly from Medela, (it’s called Symphony), or older ones from NCT, (which is what I have and it does the job). I get out between 100 and 200mls in a sitting, (3 weeks pp).
I tried a manual Tommee Tippee with dc1 and found it really rubbish, but that might just have been my technique / lack of supply.
