Hi, I don't believe there is much value in either i'm afraid as, generally speaking, both names make use of very poor English. That said, cure.rs,
does have a little potential for the meat industry, as a site that somehow deals in "cured" meats, etc...
When looking at a "hack" it's vitally important to look at 3 primary areas:
1. Does the domain aspect (to the left of the dot) stand on it's own and can it be referred to verbally?
For example, game.rs is a great hack because "game" is a fully-fledged word in it's own right, and so verbally the hack is simply stated as "game dot rs". In the case of your lone.rs name, however, you would need to spell out every letter verbally because most people would get confused with the more popular word "loan" instead.
The exception to the above is if the hack is so good that it doesn't matter so much about whether it passes the fabled "radio test", and you simply believe it will succeed regardless, e.g. doma.in (not mine, just an example).
Of course, this is where the majority of hacks occur/exist so it is perhaps not surprising that "hack discussion" inevitably keeps going back to the "radio test" conversation. I'm not sure this matters as much now 'though, as we now live in a world where presidents are tweeting what they're doing next and when did you last listen to the radio or hear someone tell you a domain
verbally anyway?!..
Staying on that subject just a moment longer, it's important to realise that many ".com" names don't pass the radio test either!
2. Is the hack commercially strong?
A gaming hack, for example, may be strong because games are a subject area that is enjoyed by many people and the opportunities to make money there are very great indeed. Curing meat, or loneliness 'though, are not great subject areas and there isn't a lot of money in them or indeed opportunities to profit, therefore a "hack" that underpins these subject areas won't be worth very much.
3. Is the ccTLD/gTLD any good?
In the case of ccTLD's, you really need to ask the question whether the jurisdiction, or country that represents the TLD, is sound. For example, n.et is an unbelievable hack but would you really want to own a hack that is governed by Ethiopia?!.. No disrespect at all to the country, I am sure it is very beautiful there, but they don't have any infrastructure to speak of or even laws for that matter, so the domain could be taken from you at any moment and you wouldn't be able to do a thing about it.
As for gTLD's, you simply need to assess whether the company that is offering them is stable and secure.
