You should try them all...no right or wrong here...all fresh milk below...
Farmhouse - Most creamy & sweet. Has a light vanilla type smell. Foams very well & most stable. Can foam much hotter before burning. Very consistent season to season. Most cafe uses it.
Goodday - Same company as Farmhouse. Just used to be OK...but last 1-2 years improved A LOT! Must try!
Pura - For the price, you can get better. I don't feel any thing really stands out. It's not bad per se...just...ordinary feeling IMHO
F&N - Same company as Pura. Used to be quite good...but now just average. Has a nice smell. Very inconsistent...you can tell the difference between seasons. QC also not great...many times turn to yogurt...my Mrs likes this yogurt / cream for baking... lol... a lot of cafe uses this milk because it is cheap
Tesco, Farm fresh, some flower picture brand - these all taste, smell, froth about the same. I'd get Tesco because it's cheaper...
If you are learning to froth, Farmhouse is easier and you can really stretch it...yes it's expensive and it makes you really pay attention to what you are doing

. It also goes very well with coffee that has more chocolate, toffee, caramel flavors.
For fruity, flower, spicy coffees, I prefer milk like Goodday & Tesco. Farmhouse is too rich and over powering.
Goodday is well balanced between Farmhouse & Tesco. Foam quite well too. It's great value when offers at RM 6...
The UHT milks' can froth OK but it's not stable. For example, Farmhouse art can stay the same for 20-30 minute...UHT will start breaking down in 3-5 minute...
Based on my knowledge.
F & N (Magnolia Yellow Box) and Farmhouse are distributed by same company F & N. Goodday is by Etika Dairies, used to be Permanis i.e. Pepsi
I use the Farm Fresh, Summerfield and Tesco. Support local farmers. And of course they are fresh but cheap.
I dont really picky on the milk selection. As long its does not have strong smell and taste that can change the coffee taste. Reason I never use Marigold H.
One of these day I must try Goodday..
