First off, yes, if you use Wordpress you will be a target for hackers, crackers and general no good doers. However, if you don't use nulled themes or plugins, keep everything updated as soon as updates are available and use some general security plugins (Wordfence being just one of the better ones) then you should stand up against them.
However, with these hosting companies that cram as many accounts as humanely possible and then some to make more money from a server then you can guarantee that somewhere on that server is someone who doesn't give two shits about security. Perhaps they set WP up on their account to test something and then left it to rot. That account could, depending on the access they get from a hack, then compromise your account on the same server.
For hosting, anything EIG related I advise people to run away from. They may be a huge money making machine but that doesn't mean they do things right. In fact the evidence shows that they buy different hosting companies, Hostgator included, and then cram all the users onto their own servers. That then cuts down on costs and ups the revenue.
However, support goes out the window - they have the minimum support needed and the majority of the time its outsourced to some company that gets paid by the ticket. They need volume of tickets to make money so you won't get personalised support. YOu will be another cash cow on the hosting merry-go-round.
Now, from your own side of things you have to weigh up whether you want to pay a few extra bucks and get a decent provider or penny pinch and go with one of the so called 'big names'. Back in the days when I had a couple of hosting businesses my prices were about 4 times (at least) that of Hostgator, GoDaddy etc and you know what, I still had more customers than I could deal with if things went tits up. However, I did the support, they got to know me and I got to know them. It was still business but had the personal touch. That helped when datacentres had outages, people were more understanding but believe me, they got their money worth out of me.
There you go, a mini rant of a pet peeve of mine - base your hosting not on the price you pay, but the price you would pay when it all goes tits-up. So you say you make $xxxxx a month on your new super money making method, so why are you hosting with a $x plan? Just because they are 'popular'? Think long and hard, thats all I am saying.
