Having the company pay for the investor's legal fees is an indication of the investor's investment model.
Paying the investor's legal fees is consistent with investing for cashflow. This is by far the most ordinary investment model. It is expected that returns are periodically realized cash.
Another investor model is to realize profits through capital gains -- not uncommon with Silicon Valley investors, but less common elsewhere. Taking capital out of the target investment at the start provides lower expected return because that money doesn't compound within the company.
Basically, the difference is that one investor sees better investments outside the company and the other doesn't. Good luck.
