Hello :-)
Where are you from?
In the US, the Zhumell z8/z10 is the best deal. In Europe, the GSO Deluxe (though it's not quite as good).
Else the Skywatcher dobsonians.
The Orion XT dobsonians come with very basic accessories (even compared to the Skywatcher dobsonians, they only have the simpler red dot finder). The XT 8 Plus seems a nice set, but the 2" DeepView eyepiece isn't showing a significantly larger field of view than a $20 Plössl eyepiece.
The beginner kit may seem tempting, but rather than the simple achromatic barlow, consider a dedicated wide-angle, long eye-relief eyepiece. Not a short Plössl though (eye-relief). CH / US

Sun filter is nice, but easy and relatively cheap to make. Also note that the sun in visual spectrum does not show structure you may have seen on pictures made with different type of telescopes.
TL;DR: Zhumell z10 > GSO Deluxe 10" > Skywatcher 10" > XT10 > Any 8" in similar order
