Do companies prefer Tier 1 (General) than dependent visa?

Dear Friends,
I am planning to move to London soon and have some queries regarding the visa system of UK. My wife is planning to pursue her master in London and as a dependent I am getting full time work permit of UK. How easy is it to get job with this type of visa? What is specific name of this type of visa? Do the companies prefer Tier 1 (General) –High Skilled visa holder than dependent visa full time work permit visa? I assessed my eligibility for Tier 1 visa and I found I have enough points for this.
Just to let you know, I have MBA from Webster and Master in ERP Systems (SAP) from Australia. I am also SAP certified consultant. I will be looking for SAP Graduate position in London.
I would highly appreciate your guidance on this.

Employeer dont look at the visa type as long as you assure them that you have a valid visa to work and it can be extended and its having for longer duration.

Agree with previous poster. It doesn't matter to the employer. Only thing that matters is that you are eligible to work in UK, and that your visa isn't expiring soon (more than 1 or 2 years is preferable). It's useful to place on your CV the line "Eligible to work in the UK. No work permit required".

For the purpose of settlement in the UK (after several years), it is better that either you or your wife has a work permit/tier 1. But for work, being a student dependent makes no difference.
