Looking to retire the desktop and move over to laptop only due to the smaller footprint and a growing family. I snagged a few laptops over the past couple weeks so I have my options open and plan on returning all except one.
I am by no means an avid gamer, but I do dabble in some games from time to time and I'd like the laptop that I keep to be up to the task. Currently the game I most frequent is World Of Warships, with older shooters like BF4 very occasionally.

The 3 I picked up are:
Lenovo Legion Y7000 $799
-i7-8750H, 8GB RAM, 256GB PCIe SSD, 15.6 1920x1080 IPS screen (60hz), 6GB GTX 1060 Max P
- USB Type-C port, Mini DP port, USB 3.0 port, HDMI port
--Has another bay for an additional HDD

Acer Nitro 5 $599
-i5-7300, 8GB RAM, 256GB PCIe SSD, 15.6 1920x1080 IPS screen (60hz), 4GB GTX 1050 Ti
- 2x USB 2.0, 1x USB 3.1 (Type-C), 1x USB 3.0, 1x HDMI
--Has another bay for an additional HDD

Dell G5 $749
-i7-8750H, 8GB RAM, 1TB HDD + 128GB SSD, 15.6 1920x1080 IPS screen (60hz), 4GB GTX 1050 Ti
- 3x USB 3.0 (1 /w Power Share), 1x USB 3.1 Type-C GEN 2 /w Thunderbolt 3, 1x SDXC Card Reader, 1x HDMI 2.0

I understand that these are entry level gaming laptops and they won't play BF1 on ultra settings, and that battery life isn't comparable to something more efficient. But out of these 3, price in mind, which is the best bang for the buck if I want to keep playing some games and don't want to constantly have to be plugged into the wall?
Part of me is leaning towards the Legion just due to the 1060 vs 1050, but not sure how much that will matter with the games that I play. The G5 is definitely a nice choice because of the lack of need for more storage (either of the other two I would plan to get an additional HDD/SSD right away). The Nitro appeals to be just due to the fact that its $150 less than the next one up, but that has a one generation older processor, no HDD, and a 1050. Not sure how much that i5 hurts it. Thoughts?

Do you know the suffix on the i5-7300? There appears to be a 7300U and 7300HQ. I'm guessing it is the HQ.
Maybe add links to the product pages?

Anyways, the Legion is definitely the best for gaming. 1060 6Gb Max-Q is going to offer ~30-40% more performance than a 1050Ti.
That is a $1200 laptop you got for $800. Strong processor, strong GPU, decent screen, and sounds like decent storage capability.

The Legion should give you an extra year of decent gaming potential over the 1050Ti, and the 8750H will give you an extra 2-3 years of strong CPU performance over whatever i5-7300 in the other one.

The Dell is also a pretty good deal with decent gaming capabilities.
The 1060 6gb Max-Q is probably ~$150 upgrade over the 1050Ti but you get a 1Tb HDD in its place. I'm not overly familiar with laptop storage prices but pretty sure you should be able to find something that would work for <$100. Hell 1Tb 2.5in SSDs have been seen at ~$110-$120 recently.

Stuff that might factor in but is purely personal preference is the looks/styling, size, keyboard/touchpad feel, and battery life.
