What to choose between these 4 laptops for programming?

[Masquerade908]

Hello, I am in the market for a new ~$600 laptop. It is okay to go a little over or under if necessary. I will mainly be using it for programming in school. I have a good desktop already so I do not need huge storage (so I prefer SSD) or a dedicated GPU for gaming (I don't plan on programming or rendering any games by the way). Googling has led me to a choice of these 4 laptops (any other suggestions welcome) and I was wondering which one out of these 4 would be the "best" in your guys' opinion:
ASUS Zenbook UX305UA (AKA the Mac clone)
ASUS F556UA
Acer Aspire E 15
Lenovo ThinkPad 13 (If this should I get the Black or Silver edition?)

Thank you for your help

If you need portability, then the 13" laptops will be half the weight and is probably best for your usage.

I think Lenovo generally has the better keyboards.
Here is a review; you might want to compare reviews of the others:

The key to performance on a laptop is the ssd.
I have had great success buying used/refurbished laptops with minimal ram and a small hard drive.
Adding ram and changing to a ssd is not expensive.
One of the best is the Lenovo T430s. The s variants are lighter. You can find them on ebay for $250 or so, depending on what is inside. Some come with a discrete graphics chip for light gaming.
They are usually corporate units that have come off lease and cleaned up.
And... they come with windows 7, not windows 10 which is a plus in my book.
Here is just one example.

Add a Samsung 250gb ssd, you can use their clone utility to migrate.
I have done this to two T430s units with no issue.
