Evaluating Opportunities: CTS vs. PwC
First thing, I really want to know how you have judged and found that CTS can provide you with better onsite opportunities.
Have you considered the market cap and opportunities that PwC and CTS have in hand today and are expecting?
What do you feel or expect from PwC concerning your career enhancement compared to CTS?
If this is just a concern of salary, I would suggest that the way you are looking at CTS, thinking it will give you more and better work opportunities than PwC, you need not consider salary at this time. New and best opportunities themselves bring good and higher salaries with respect to the experience earned by one (you, or any candidate).
The more experience and knowledge you gain, the more you will have good opportunities that will boost your confidence and career growth.
See, these things actually matter to recognize first.
However, if you feel the market conditions and the grasp of CTS on it, along with the present work opportunities/projects (today's market cap and the expectation of many more good business opportunities) are better than PwC, you can go with CTS. But I would suggest you go with PwC, which I personally feel is best. There are many more reasons to say this, but I would suggest you conduct research yourself, which would certainly help you in this.
You need to visit their company profiles for current and ongoing projects/work, market cap, and current and expected work options. You can get much more information by visiting their website and business information websites.
