。
I think this one is worse than that one.
Literal
I [topic-は] that-side [than-より] this-side [of-の] direction [subject-が] inferior [quotative-と] think.
おとる (劣る, 'to be inferior to') takes より for the standard of comparison. This sentence inverts the usual preference framing: [Aより Bのほうが] is usually used with 好き, but here with 劣る ('inferior') it expresses 'B is worse than A.' Note the ending ~と思う framing the claim as personal opinion.
