Hello, I'm on the market for a good high quality reel. what would be the best all around reel out of the following four:

Metainium mgl

Daiwa steez sv tws

Daiwa steez sv

Shimano aldebaran

(Feel free to suggest anymore reels).

It's all subjective on reels, especially when you get to the top of the line reels like the ones you listed. The best thing to do is get somewhere you can handle them and decide which one feels the best to you. 

I have the  Daiwa steez sv tws, very lite and good casting reel. Takes little effort to cast. Very few backlashes. The only time I really get a backlash is using smaller braid and it digs. 

It depends on what your goal is for a reel selection; casting light weight lures into the wind, light reel weight, durability, functionality, resale value or bragging rights.

All the high end reels are exceptional casting reels.

At that price range it comes down to personal preference. You can't go wrong with a high end reel from either of those companies. 

what type of breaking or how it feels in your hand.  Which shape fits your hand.  They are both the best companies and do you want to drive honda or toyota.  

When you are comparing those reels it comes down to what feels better to you.

The reels listed are out of my league.  I feel sure that what everyone else has said is true.  Pick the reel that feels the best to you.  Do you prefer one type of braking over another?  Does one pique your interest more than the others?  I'd buy the one that interested me the most.

As for alternatives, I can suggest a couple if you decide to save a bit of money.....since I don't have reels in that price range.  Two reels that have impressed me are the Primmus and Helios Air.  Both are excellent casting reels.  I find the Primmus to be a more set-and-forget reel than even my Shimanos.  Both are quite light if that is important to you....as it is to many these days.

As everyone has said at that price point they are all good. I will say this,I have many Shimano reels with over half in the high end range.  I have 2 Daiwa Zillion 100 SHLA's that are very good reels. Here is what I notice, When I have been fishing a few hours & switch to the Daiwa set up  it takes a couple of minutes to get use to it.  It bothers me enough that I have ordered 2 Shimano Scorpion's 201XG's to replace them. I guess I just like all the same brand.
