French vs. Scandinavian

The Modern Scandinavian is great if you enjoy open and sharp positions and I'm doing very well with it. 99% of the time you're not gonna be getting the critical lines and a lot of the time white premoves Nf3 or Bc4 and hangs something.

SCANDINAVIAN 

the scandinavian is simpler to play for someone starting out, but later on this could be a drawback once you get stronger. there is not much crossover between the scandi and the french so if you are looking for long term i would recommend the french instead. might be difficult starting with it but you don't need to worry about it being outgrown by your playing strength.

if you don't mind risking some, then you could still go for the scandi route. there are sharp lines in the nf6 versions, and also even in the qd6 and qa5 lines. personally i just think white has more of an advantage here than what he can get vs the french, and usually to get there white has to overextend somehow, while in the scandi he rarely has to.

French Defense, but I would recommend playing the dxe4 variations (rubenstein) until you get higher rated, as many people will not play Nc3 or Nd2. 

I think both are good options for inexperienced players - I agree that if you choose the French you should go for the dxe4 lines, which are solid and easy to learn. However, you will also need something against the Exchange (fairly easy to deal with), the Advance (more complex, but worth knowing since the ideas are fundamental to the French generally), and the King's Indian Attack (sophisticated, but not so popular at lower ratings). The Banker variation of the Scandinavian (Qxd5  followed by Qd8) is very straightforward, and White doesn't have a convincing alternative to the main line, so it would be my choice.

french might not be liked by everyone, but it is UNQUESTIONABLY better than the scandi

The scandi is an opening you play in blitz/bullet, and nothing else if you are over like 1800

I played the scandi when I was between 1500-1700 strength, but after I got to 1700 people began to counter it and it just doesnt work in long time controls after that

In my opinion, I would say french. It is better than the scandi, almost no question, but it isn't for everyone. For me, I would be lost and get completely locked out with the french, but I enjoy playing against it. Scandi is a slightly inferior opening, but it isn't trash. whatever you do though, don't move only your queen, and don't do this.

Scandi Qxd5 is just slightly worse with very little complication

Portuguese is very tricky, but white can get a big advantage if he plays perfect and also there is a slightly better version that made me give up the line 

What line is that?

3. d4 Bg4 4. Nf3 Qxd5 5. Be2

It's nice to see members of Team Caro-Kann promoting the French Defense.  For a player at the OP's level, I would caution that the French Defense requires active play on the part of black in order to be effective.

In the French Defense, you can avoid the early main line restriction of the light square bishop by playing the Rubinstein Variation (which I would recommend for players who prefer an open center), but you'll still need to know how to undermine the pawn chain if white plays 3. e5 (the Advance Variation) instead of 3. Nc3 (main line) or 3. Nd2 (Tarrasch Variation).

Uhm, what opening does not require active play by Black?  Even the Berlin requires active play, giving up the dark-squared Bishop for a Knight being very desirable, and dominating g4 and the light squares, and also avoids 2 of Black's worst endgames (Same color Bishops or White Knight vs Black Dark-Squared Bishop).

All of that requires active play, so the French is no different!  You cannot sit back in the Scandinavian either, and the Scandinavian is inferior to the "big 4" (e5, e6, c5, or c6).
