If bottle feeding is your informed decision then it should be supported.
I would be very wary of claims by your friend about the best brand though as there is absolutely no robust evidence supporting this. All you need to know is to use a first stage milk for the first year and then move on to cows milk. No need for any fancy formulas or follow ons. Sadly formula companies target professionals a lot in their advertising through sponsored study days etc but I can promise you that all formula are nutritionally equivalent and there is not one that is best. The brand you mention is a relative newcomer in the UK and has used some very pushy and very underhand tactics to try to get itself known. Fine if you want to use it, but do have a look at the evidence first.
First Steps Nutrition is an excellent, evidence based resource for formula feeding. You can find out all about different brands, what goes into them and why they are all the same! I would encourage you to really think about this, after all it is the first food your baby is going to have. I don't mean that to be patronising but if you think about it, most of the marketing is about fooling you in to spending more than you need to. One company makes two different milks in the UK, one of them is the cheaper £10 a tub milk and one is the super expensive £18 a tub. Why would they do that when the nutritional value is the same of not to make money?
I would encourage you to do the first feed in skin to skin after birth, it has a lot of benefits for you and your baby. Skin to skin is for bottle feeding too! You can keep doing some skin to skin feeds for those lovely snuggles after too. It will help keep baby warm, support her immune system by helping colonise her microbiome from you and release lots of hormones to calm both of you which will help all that lovely bonding you've been doing in pregnancy to strengthen. Your partner might be eager to do it too but they can wait! This period is actually really important for your baby to spend with you if possible.
Have a look at paced bottle feeding, so keeping baby close and quite upright, inviting her to take the teat and keeping the bottle pretty much horizontal with the end of the teat just filled with milk but still having an air gap in the teat. This means the milk won't just keep dripping into her mouth and she will have control over her feed. If she pauses you can lower the bottle (without taking the teat out of her mouth) and then lift out again when she starts the suck. Look out for signs she wants to finish the feed like splaying her hands or pushing the teat out.
Always look at the baby not the clock, feed her when she shows feed cues, yay might be at different intervals and she might take different amounts each time. That's fine. And limit the number of people who feed her to just her main caregivers not everybody who fancies a cuddle!
