Cacao genes from the Mars/USDA sponsored project are at top in plant gene-set completeness.
These were built using mixed methods that include more mRNA-assembly than genome-gene models.

Banana genes assembled only from mRNA are about as complete as banana genome-gene and
and amborella genome-gene sets.  Banana expressed mRNA-seq has
about 10% fewer orthology groups than the genome-set, a rate I find
generally for various species.

    Bits  = bitscore from blastp, for groups common (cBits) to all and for 
            all (aBits) families with 3+ plants
    dSize = protein size difference from family median
    Tiny  = count of tiny protein size outliers (-3sd below family median)

Notes: cacao1ma, orange1cn, banana1g are best of 2 independent gene sets for 
those species.  cotton is close relative to cacao and its gene set has been 
built using the cacao1ma gene set (among others).  Bitscores are influenced
by phylogeny as well as quality, scores by alignment (somewhat less phylo-dependent)
show same ordering.  Protein size is closely +correlated with bitscore.
Ranking quality by protein size and orthology families (nGroup) gives similar
result, but arabido.th and brassica move up to middle (6,7th).
