LONDON -- In this series, some of your favorite FTSE 100 (UKX) shares go head to head in a three-round contest for superiority.

In Round 1, the firms fight on earnings; in Round 2, on dividends; and Round 3 is a battle of the balance sheets. The winner will be the company that has racked up most points at the end of the contest.

Stepping into the ring today are support services groups Capita (CPI 1.21%) and Aggreko (AGK). Capita is focused on white-collar office support services; Aggreko could be described as more blue collar, supplying temporary power generation and industrial cooling and air conditioning.

The shares of both companies have outperformed the FTSE 100 over the past year. The Footsie is up 7%, but Aggreko is up 19% and Capita 21%.

Let's take our seats at ringside.

Post-match assessment
This was a comfortable win for Aggreko. Capita managed just four points -- for historic and forecast P/E and dividend yield -- but while these "value" scores are good relative to Aggreko's, they're not particularly generous compared with the average for the FTSE 100 as a whole.

Aggreko's victory in the contest was driven by very strong growth of earnings and dividend. It also has a decent operating margin and fairly modest gearing. However, while a high P/E of above 20 doesn't look unreasonable against Aggreko's historic earnings growth, it looks less attractive when considered against the more modest growth forecast for the current year.

Aggreko's growth will have to return to closer to the historic rate to justify a P/E in the 20s. For me, the company looks fully valued at the present time.
