and that is one of the main reason so many dogs end up in rescue in this country 
People buy a cute pup they like the look of with no idea how they are going to meet that dogs need when its older
Ummmm, no, I am not talking about the look of a "cute pup", I am talking about liking the look of the adult dog.
I am beginning to wish I hadn't posted this thread.
No of course look comes into it - The first thing that attracted me to cockers was the 'look' of them... but I looked after one (a show type) for a while before I got my own so was sure I could handle their energy and mischievous streak. I have a Weimaraner as well and I love the look of Weims but also knew enough about them to know it really suited our active life style and I love the challenge of training and living with gundog type dogs - with all the problems and rewards it brings. I'm not very good at other types of dogs tbh

I also absolutely love the look of English Bull Terriers but I KNOW I'd find them a frustrating breed to live with and they wouldn't suit us.
Dealing with a dog with a high hunt drive (as all gundogs and in particular working bred strains can have) can be extremely hard work and give you years of frustration.. my Weim is a rescue (there isn't a working/show split for Weims but she comes from working parents and has a high hunt drive) that I took on aged 2 from a home that decided that she didn't really suit their life style afterall. They had done all the usual puppy classes with her but hadn't put the time into exposing her to enough of what she was bred to do or channeling her working instincts. So she hit 2 years old as a big fast inexperienced dog with a very strong hunt drive and was totally out of control - I lost her every walk for up to 40 mins despite constant training, stimulation and help from anyone that would give it to me

Even very experienced owners can struggle with very high hunt drive gun dogs - even when they own them from being a pup.
So I guess what I'm trying to say is whilst look is a factor, you are looking at taking on a hunting breed which can be a very big issue if you want to focus on having fun & long walks rather than channeling their instincts all the time - hope that makes a bit more sense?
My Weim is 5 now and a very wonderful obedient dog but I have to be one step ahead of her all the time and train her every day still, both my show type cockers have had periods of deaf bogging off after rabbits etc but both were a bit less obsessive about it than the dog with the very high hunt drive - which is something you are likely to get in a working cocker...
Please don't think people are having a pop at you, lots of the people advising you own workers and have been involved in rescuing workers that ended up in pet homes and couldn't be managed effectively so it's advice given with very good intent I promise
