Ranking with myKeyword.com vs Keyword.com (experts please)

Hi, i would like experts or people with experience who have set up many sites who can answer some question i have on domain names.

Will something like "imKeyword.com" rank as easily and as well as just "keyword.com" for the search keyword?

also, say i want to rank for a three word keyword example

Word1 Word2 Word3 is the phrase/keyword

the site "Word1Word2Word3.com" is already taken

if i register the site "Word2Word1Word3.com" will it rank equally well for the keyword?

thank you in advance

yep if the niche is not over saturated.... ie more then 1 million searches in G for that keyword. As long as your main keyword is in the domain your good... but get creative keywordinfo.com etc. I use G keyword tool set to show all and go after the high paying niches with the above formula... works like a charm...
and works well for quick checking domains not yet taken..
