Everyone will tell you something different is the best one for a beginner, I look at it a bit different. there are basically two roads you can go down, New Modern razor, or antique old razor, and on those two roads there are endless choices of houses to stop at, from really expensive to dirt cheap, supper mild to scary aggressive.
All I can really share is my personal trip in to DE shaving. I was getting really bad ingrown hairs on my neck and have a huge scare on my chin that would get nicked every time I shaved with a multi bladed razor. I didn't want to buy a used antique razor at that time so I listened to what a lot of people said and read a lot of reviews to see what had the better chance of working for me and fit my budget. I ended up getting a Edwin Jagger DE89L, not an expensive razor, but looked to do what I needed it to do for me. Then there was the blade choice thing, many people will tell you that you have to use blade X and to ignore any irritation you may be getting from it. Stating that it isn't the blade and razor causing the problem its your technique and to stick with it. I on the other hand am dead against that and feel its better to learn with a mild razor and blade and get good with that before using a super sharp blade and aggressive razor. To this day I can not get an enjoyable shave out of a Feather blade unless I stick it in my mildest razor. I have the same problem with Derby blades except even in my mildest razor they wage war on my skin
I have since moved on to old Gillette razors and like them better than DE razors made today. I got over the used razor thing when it was pointed out to me that we reuse our silverware every day, and that the razor only holds the "new" blade. That old razor can be cleaned and sterilized quite easy so its not a problem
If you want a cheap quality razor to start off with find an old Gillette Tech, they are simple and very forgiving, don't pay more than $10 for one, they are a dime a dozen. For a more modern razor, any of the Edwin Jagger DE89 line can be picked up for $30-$50 and the same goes for the Merkur HD line. Those are probably the two most recommended beginner razors out there, and they hold that position for a reason. Get a blade sampler pack from one of the many online retailers, but don`t use a different blade each shave. Use each brand long enough to get a feel for it, but obviously if a particular blade is causing discomfort and pain while shaving, STOP!! you are doing something wrong. Do a bit of reading on technique and prep because even a blade that doesn't work for you, your face should not hurt while shaving.
Right now my go to setup is a Gillette New Standard, with either a Persona Red or Blue blade, used with Proraso Green shave soap, followed by some Captains Choice bayrum aftershave, but I have over 20 old razors and I switch it up from time to time depending on my mood. That is what works for me, but it is in no way saying it would work for you.
If you are playing life on easy, you are never going to win when it counts
