It really depends on what your looking at playing. There are multiple different formats.
Standard
Pauper
Pioneer
Modern
Commander
Legacy
Vintage

I would recommend if you are a newer player, maybe getting into standard might be fun, as it is fairly easy and can be cheaper(Since most packs are still available and in print)
The only downfall of standard is, as new setblocks come into rotation, the old ones come out, so in a way, your always looking into purchasing cards to keep up to date with standard.
As for other formats, it's in a way harder to get into, as there are so many more cards out there from earlier dates that can be harder to find/obtain.
There are also formats that are more limited (Sealed/Draft) Where it's a fee each time you play
Sealed you get 6 boosterpacks, and you make the best deck out of the cards from those packs(Your Pool), it really helps having some knowledge to the game, so you can learn how certain cards synergize really nicely with each other
Draft you get 3 boosterpacks, and sit at a table with mulitple players (Normally 8), each person opens 1 pack, pulls a card from it, and passes it to the left or right(Rotates for each pack). And then once all cards are distributed you build the best 40card deck out of your pool(The cards you picked)
I wouldn't recommend the limited formats unless your more familiar with the game, expecially drafting, cause having knowledge of the entire set that you are drafting and synergies of the cards in the set, can really help with your choices for what you are picking out of each pack your handed.
