Average temperature variation for 6 degrees tilt is probably only 1 or 2 degrees (sunlight per unit area should be proportional to [1/cos tilt-angle] squared and 6 degrees tilt gives about [edit] a sixteenth of the variation that 23 degrees tilt does at the equator and about a 24th outside the tropics)

So including the 14 degrees for eccentricity you are looking at perhaps 16 degrees overall average annual temperature variation.

Its seasons will be more extreme near the equator than Earth's but less extreme overall. Earth's equator only sees the temperatures vary by single digit degrees. Whereas Earth's poles see something like a 30 degree variation over the year.

Earth does get a theoretical 4 degree temperature variation with it being warmest at perihelion around 4th January each year (southern hemisphere summer), though the oceans buffer the rise.
